Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

As shown in FIGS. 1 to 4 , a demolition robot arm provided in one embodiment of the present application includes:

A connecting seat 1 is hinged with a main arm 2, and the other end of the main arm 2 is hinged with a secondary arm 3. A hydraulic push rod 4 is hinged between the main arm 2 and the connecting seat 1 and between the secondary arm 3 and the main arm 2. The main arm 2 and the secondary arm 3 are hinged to each other to form a bendable structure, which increases the extendable height and length of the device, wherein the width and length of the main arm 2 are greater than the width and length of the secondary arm 3, which is used to increase the movement stability of the device;

The demolition chuck 5 comprises a flip seat 501 hinged at the end of the auxiliary arm 3, a hydraulic push rod 502 is hinged on the upper side of the auxiliary arm 3 along its length direction, the movable end of the hydraulic push rod 502 is hinged to the flip seat 501, and a hydraulic clamp 503 is fixedly connected to the flip seat 501, wherein the hydraulic push rod 502 mainly drives the flip seat 501 to flip relative to the auxiliary arm 3 by telescoping, so as to control the orientation angle of the hydraulic clamp 503 and increase the flexibility of the device;

The water spray assembly 6 comprises a continuous spray pipe 601 and an intermittent spray pipe 602 fixedly connected to the upper and lower sides of the hydraulic clamp 503. A blocking block 603 connected to the hydraulic clamp 503 is slidably installed in the intermittent spray pipe 602. The continuous spray pipe 601 is arranged on the upper side of the hydraulic clamp 503, which has the effect of continuous water spraying. It is mainly used to water and cover the building wall that needs to be demolished, and can also water the movable end of the hydraulic clamp 503, which can not only play a dust reduction effect but also play a cooling effect on the hydraulic clamp 503. The intermittent spray pipe 602 is connected to the hydraulic clamp 503 in a transmission manner. By utilizing the blocking and opening action of the blocking block 603, the opening of the intermittent spray pipe 602 can be opened when the hydraulic clamp 503 is clamped, so as to provide additional watering for the demolition part. When the hydraulic clamp 503 is opened, the blocking block 603 closes the intermittent spray pipe 602 to increase the water-saving ability of the device.

The water storage pressurizing component 7 includes a water storage tank 701 fixedly connected to the main arm 2, a water pumping pipe 702 is installed through the water storage tank 701, and a gas filling component 703 connected to the hydraulic push rod 2502 is installed on the auxiliary arm 3. The gas filling component 703 and the water storage tank 701 are connected through the air transmission pipe 704. The water storage tank 701 is mainly used to store water, so that the device can be used independently outdoors to increase adaptability, and the gas filling component 703 is mainly used to add gas to the water storage tank 701, thereby increasing the pressure in the water storage tank 701, so as to facilitate the water in the water storage tank 701 to be injected into the continuous spray pipe 601 and the intermittent spray pipe 602 through the water pumping pipe 702, so as to facilitate spraying.

As shown in FIGS. 2-3, in some embodiments, the flip seat 501 includes a U-shaped seat 5011 with one end hinged to the end of the auxiliary arm 3, and the other end of the U-shaped seat 5011 is hinged to a push rod 5012, wherein the bottom corner of the U-shaped seat 5011 is hinged to the end of the auxiliary arm 3, and the top corner is hinged to the push rod 5012, and the other end of the push rod 5012 is hinged to an arc rod 5013, and the other end of the arc rod 5013 is hinged to the auxiliary arm 3 to form a quadrilateral, and the movable end of the hydraulic push rod 502 is hinged to the push rod 5012. The quadrilateral formed at the hinged end of the movable rod 5012 and the arc rod 5013 has a stable supporting structure, which makes the hydraulic clamp 503 more stable when moving. When the movable end of the hydraulic push rod 502 is extended, it will drive the hinge point of the push rod 5012 and the arc rod 5013 to move toward the U-shaped seat 5011, thereby driving the U-shaped seat 5011 to flip downward. Conversely, when the hydraulic push rod 502 is contracted, it will drive the U-shaped seat 5011 to flip upward, thereby adjusting the direction of the hydraulic clamp 503 and increasing flexibility.

As shown in FIG. 4 , in some embodiments, the hydraulic clamp 503 includes a Y-shaped seat 5031 fixedly connected to the bottom end of the U-shaped seat 5011, two parallel connecting rods 5032 are hinged at both ends of the bottom of the Y-shaped seat 5031, and the other ends of the two adjacent connecting rods 5032 are hinged with triangular claws 5033, and a hydraulic pull rod 5034 is installed through the Y-shaped seat 5031, and the output end of the hydraulic pull rod 5034 is fixedly connected to a connecting plate 5035, and both ends of the connecting plate 5035 are hinged with a pulling rod 5036, and the other end of the pulling rod 5036 is hinged to the middle of the connecting rod 5032, and the connecting plate 5035 is hinged to the connecting plate 5035. Two parallel connecting rods 5032 are respectively arranged at the two ends of the bottom. The connecting rod 5032 close to the outside is used to increase the stability of the connection, while the two connecting rods 5032 close to the inside are used to be hinged with the pulling rod 5036, so as to move with the extension and retraction of the hydraulic pull rod 5034, thereby driving the triangular claws 5033 to move closer to or away from each other, thereby increasing the structural strength of the device. When the hydraulic pull rod 5034 contracts, it will drive the connecting plate 5035 to move together. At this time, the two pulling rods 5036 will pull the two connecting rods 5032 closer to each other, thereby driving the triangular claws 5033 to produce a clamping movement.

As shown in FIGS. 5 and 6 , in some embodiments, the intermittent spray pipe 602 includes a vertical pipe 6021 fixedly installed on the flip seat 501 and located on one side of the Y-shaped seat 5031. The vertical pipe 6021 is arranged on the lower side of the Y-shaped seat 5031, and the continuous spray pipe 601 is arranged on the upper side of the Y-shaped seat 5031. At this time, when the hydraulic clamp 503 is aimed at the wall to be demolished, the continuous spray pipe 601 is on the upper side of the hydraulic clamp 503, and can continuously water and cover the part of the wall to be demolished, thereby reducing subsequent smoke and dust. The vertical pipe 6021 is arranged on the lower side, which is used to spray additional water on the fallen gravel during the demolition work, which can increase the dust reduction effect and save water resources. The end of the vertical pipe 6021 facing the triangular claw 5033 is constructed with an annular baffle 6022, and the annular baffle 6022 is fixedly connected with a conical spray pipe 6023. The blocking block 603 includes a mesh piston 6031 slidably installed in the vertical pipe 6021. The middle part of the mesh piston 6031 is provided with a sealing block 6032 for sealing the annular baffle 6022. The sealing block 6032 is fixedly connected with a moving rod 6033 that movably penetrates the annular baffle 6022 and the conical nozzle 6023. The other end of the moving rod 6033 is fixedly connected to the side of the connecting plate 5035. When the hydraulic pull rod 5034 contracts, the connecting plate 5035 is driven to move toward the Y-shaped seat 5031, thereby driving the moving rod 6033 and the mesh piston 603 1 is separated from the annular baffle 6022, so that the port of the vertical pipe 6021 is opened, so that the conical nozzle 6023 can produce a water spraying effect. When the hydraulic pull rod 5034 is extended and the triangular claw 5033 is fully opened, the sealing block 6032 on the mesh piston 6031 will block the opening of the annular baffle 6022, thereby blocking the vertical pipe 6021 to prevent water from leaking out. Intermittent water spraying is performed with the movement of the hydraulic clamping claw 503, thereby increasing the water-saving effect of the device.

As shown in Figure 6, in some embodiments, the moving rod 6033 includes a conical diverter block 60331 fixedly connected to the side of the connecting plate 5035, and a column 60332 is fixedly connected to the conical diverter block 60331. The other end of the column 60332 is connected to an extrusion spring 60333, and the extrusion spring 60333 is fixedly connected to the sealing block 6032. When the conical nozzle 6023 sprays water, the water will be sprayed along the column 60332 toward the conical diverter block 60331, and the conical diverter block 60331 will be used to break up the water, so as to increase the spraying area of the water, increase the coverage of smoke and dust, and improve the dust reduction effect. The extrusion spring 60333 is used to drive the sealing block 6032 to move when the hydraulic pull rod 5034 is extended, so as to avoid the sealing block 6032 from contacting the annular baffle 6022, thereby hindering the movement of the hydraulic pull rod 5034 and increasing safety.

As shown in FIG6 , in some embodiments, the end of the continuous spray pipe 601 is fixedly connected to a shower head 6011. It should be noted that the shower head 6011 includes a conical frame fixedly connected to the end of the continuous spray pipe 601, and an anti-conical frame arranged opposite to the conical frame is sleeved on the outside of the conical frame. The end of the conical frame is a pointed end, and the end of the anti-conical frame is a large-surface end. A mesh is constructed on the large-surface end of the anti-conical frame. When water flows into between the conical frame and the anti-conical frame, the pointed mouth at the end of the conical frame will be used to isolate the water pressure part, thereby reducing the spraying length of the water flow and controlling the water flow within the clamping range of the hydraulic clamp 503, thereby reducing the loss rate of the water flow and further saving water resources.

As shown in Figure 3, in some embodiments, the continuous spray pipe 601, the intermittent spray pipe 602 and the water pumping pipe 702 are interconnected through a hose 8 and a three-way switching valve 9 is installed therebetween. The three-way switching valve 9 is an electromagnetic control valve that automatically controls the water flow path, making it convenient for personnel to independently switch the water spraying of the continuous spray pipe 601 and the intermittent spray pipe 602, thereby increasing the flexibility of the device.

As shown in Figures 3 and 7, in some embodiments, the gas-filling member 703 includes two cylinders 7031 fixedly connected to the fixed end of the hydraulic push rod 502, and piston rods 7032 are slidably inserted in the two cylinders 7031. The other end of the piston rod 7032 is fixedly connected to the movable end of the hydraulic push rod 502. The end of the cylinder 7031 away from the piston rod 7032 is connected to a one-way air inlet valve 7033. The two ends of the air delivery pipe 704 are connected to the cylinder 7031 and the water storage tank 701 through the one-way valve 7034. When a demolition operation is required, the flip seat 501 is the most frequently moving component because the main arm 2 and the auxiliary force arm 3 have been lifted to the vicinity of the demolition part. If you want to demolish it step by step, you need to continuously flip the flip seat 501 to adjust the position of the hydraulic clamp 503, and the gas-filled part 703 uses the hydraulic push rod 2 502 as the driving force. The movement of the active end of the hydraulic push rod 2 502 drives the piston rod 7032 to move back and forth in the cylinder 7031, so as to use the one-way air intake valve 7033 to extract external air and inject it into the air pipe 704, increase the pressure of the water storage tank 701, utilize and convert the driving force, provide driving pressure for water spraying, save energy consumption of the device, and increase the linkage of the device.

As shown in Figures 3 and 8, in some embodiments, a pressurized water pump 705 is fixedly connected to the bottom of the water storage tank 701, and a water pipe 706 is fixedly connected to the other end of the pressurized water pump 705. A pressure relief valve 707 is fixedly connected to the top of the water storage tank 701. The pressurized water pump 705 is provided as an auxiliary component to provide water supply for the water storage tank 701. The water pipe 706 can be connected to the tap water pipe, and the pressurized water pump 705 is used to pressurize the water source into the water storage tank 701 to avoid insufficient water supply and increase the adaptability of the device. The pressure relief valve 707 is provided to control the pressure in the water storage tank 701 to avoid damage to the device due to excessive pressure and increase safety.

As shown in Figure 9, a demolition robot proposed in an embodiment of the present application includes a tracked mobile seat 10. The tracked mobile seat 10 adopts the existing electric tracked mechanical chassis and uses electricity to drive the tracks to move. It can adapt to various terrain movements and increase the working range of the device. The upper end of the tracked mobile seat 10 is fixedly connected to a load-bearing platform 11, and the connecting seat 1 is fixedly connected to the middle of the load-bearing platform 11. The end of the load-bearing platform 11 opposite to the main arm 2 is fixedly connected to a counterweight frame 12, and a battery 13 is installed in the counterweight frame 12. The weight of the battery 13 is used to neutralize the weight of the mechanical arm, so as to balance the center of the robot as a whole, avoid the device from tipping over, and increase safety.
