technical field

The utility model relates to the technical field of digging machines.

Background technique

In order to speed up the power grid construction project, it is necessary to take the road of industrialization, that is, to use mechanized means of production, and scientifically organize flow operations to carry out the construction of the power grid construction project. In this context, it is proposed to promote the research and development of integrated construction equipment. At present, the construction of transmission line piles mainly has two kinds of construction methods to choose: one is to manually do the retaining wall and dig holes. With the rapid development of economy and society, front-line construction personnel are in short supply, and labor costs continue to increase. The hole forming is slow, the safety is poor, and the cost per linear meter is very high. Second, the rotary drilling rig digs holes quickly and has high safety, but the cost per linear meter is high, the equipment is heavy, and there are limitations in entering and exiting the site. In the North China Plain, mainly cultivated land, most of the plantings are cash crops, and most of the roads are one-way lanes for agricultural vehicles, which sets obstacles to the use of rotary drilling rigs. According to the concept of mechanized construction, it is imperative to develop small integrated construction equipment. After in-depth research, combined with the construction characteristics of transmission lines, our unit developed a small gravity digging machine according to the actual situation on site.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

With reference to accompanying drawing 1, a kind of small gravity digging machine that the utility model provides, comprises car body, first support 110, second support 120, pulley 130, winch 210, flexible cable 220, gripper 230 and power unit; One end of the first bracket 110 is hinged to the vehicle body, and the other end is hinged to at least two second brackets 120, and a pulley is provided at the hinge point between the first bracket 110 and the second bracket 120 or at the end of the first bracket 110 near the hinge point. 130 ; the hoist 210 is located on the vehicle body, on which a flexible cable 220 is wound, and one end of the flexible cable 220 is connected to the handle 230 across the pulley 130 ; the power device is located on the vehicle body and provides power for the hoist 210 . The power unit may be an engine of the vehicle body.

Before use, all equipment is all positioned on the car body, when will use, if the first support 110 and the second support 120 have been hinged, the first support 110 and the second support 120 can be turned over the car body to form a tripod type The supporting structure, and the flexible cable 220 bypasses the pulley and is connected to the gripper 230. When in use, only the winch 210 needs to be manipulated; when it is about to be used, if all parts are in a separated state, it needs to be assembled on site. Simultaneously, for the convenience of assembly, the car body is also provided with a hand-pulled or electric hoist at a position higher than the pulley 130, and a hook is provided on the lifting chain of the hoist.

The construction technique of using the utility model is as follows: 1) Level the site, measure and place the pile points, and bury the pile points in the soil with about 3Ocm long steel bars, so as to avoid equipment and earth trucks from destroying the pile points while moving; 2) transport the gravity The hole digging machine is assembled at the construction site and powered on for trial operation; 3) Stabilize the first bracket 110 and the second bracket 120, and adjust the center of the gripper 230 to the pile head, lift the gripper 230 to align with the pile point, and open the hole for excavation ; 4) When the grab handle 230 is full of soil, it is lifted, and the earth truck with the crossbeam above the bucket is poured down to below the grab handle 230 that is full of soil, and the grab handle 230 is lowered to the cross beam of the earth truck, and the grab handle 230 will Loosen the soil to be dumped into the soil transporter, lift the gripper 230, drive away the soil transporter, relax the winch 210 and use the gravity of the gripper 230 to continue sinking to grab the soil; 5) Repeat operations like this, and dig holes to the design bottom elevation of the pile hole. In the process of digging a hole with a gravity hole digging machine, if the soil is too wet to be grasped, you can pour a little quicklime into the hole, and use the shovel head to smash the stone into the soil to make it absorb water, expand and squeeze. Dense wet soil layer, and then grab the soil in the hole. When encountering a relatively hard soil layer, an air compressor with a pneumatic pick can be used to penetrate the local hard layer and then grab the soil residue in the pile hole and transport it away.

Further, in the aforementioned small gravity hole digging machine, in order to make the hole digging operation more stable, the vehicle body also includes a hydraulic leveling device 140 .

Further, in the aforementioned small gravity digging machine, the power device includes a generator 310 , a distribution box 320 , and a motor 330 .

Referring to accompanying drawing 2, the gripper applied to the aforementioned small gravity hole digging machine includes a counterweight bin 231, a petal claw 232, a gripper main rod 233, a gripper sub-rod 234, an elastic member 235 and a gripper main rod cross arm 236 The counterweight bin 231 is hinged with at least two petal claws 232. After the petal claws 232 are closed, they form a cavity with the counterweight bin 231; the handle main rod 233 passes through the counterweight bin 231, and the middle part of the cross arm 236 of the grip main rod is fixed on the The lower end of the gripper main rod 233 is hinged to the gripper sub-rod 234, and the gripper sub-rod 234 is hinged to the inner wall of the petal claw 232; the two ends of the elastic member 235 withstand the counterweight bin 231 and the gripper sub-rod 234 respectively; The angle between the main hand lever 233 and the gripper auxiliary lever 234 is greater than 90°. The elastic force of the elastic member 235 when tightened is smaller than the gravitational force on the handle.

The use method of the gripper 230: when the gripper 230 falls, the main rod 233 of the gripper 230 does not offset the gravity of the gripper 230, the elastic member 235 stretches, and the petal claw 232 bounces off, and the gravity makes the lower part of the petal claw 232 insert into the soil, grasping When the hand 230 is lifted, the main rod 233 of the gripper 230 needs to counteract the gravity of the gripper 230, the elastic member 235 shrinks, the petal claw 232 closes, and the earthwork in the hole is grasped and proposed in the cavity.

Further, in the aforementioned gripper, the side of the counterweight bin 231 is also provided with reaming teeth 238 .

Further, in the aforementioned gripper, the upper end of the gripper main rod 233 is also provided with a suspension ring 237 to facilitate the connection between the gripper main rod 233 and the flexible cable 220 .

Further, in the above-mentioned gripper, the elastic member 235 is a spring sleeved on the lower part of the gripper main rod 233, and can also be a shrapnel, a cylinder, etc. at the same time.

Further, in the aforementioned gripper, the angle between the gripper main rod 233 and the gripper sub-rod 234 is 105°-165°. This angle maximizes smooth operation and prevents malfunctions.

The principle of gripper reaming: use the reaming teeth 238 on the gripper counterweight bin 231 to cut the pit wall when falling, so that the aperture meets the design and construction specification requirements.

In this paper, the principle and implementation of the utility model are described, and the descriptions of the above embodiments are only used to help understand the method and the core idea of the utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made to the utility model, and these improvements and modifications also fall into the protection of the claims of the utility model. within range.
