Detailed Description
The marks in the figure are respectively: 1. the support leg comprises a support leg body, a height adjusting device, a working platform, a support leg, a cross beam, a support jack, a support shoe, a tunnel excavation trolley, a support leg groove, a tunnel excavation trolley, a support leg groove and a vehicle channel.
Examples: referring to fig. 1 and 2, there is shown a freely height-adjustable tunnel excavation trolley 100 of an embodiment, the trolley having four sets of legs 1, wherein a height adjusting device 2 is installed between each set of legs 1, the height adjusting device 2 comprising: a cross beam 21; two jacks 22 respectively installed at both ends of the beam 21; and two support shoes 23 mounted under the cross beam 21.
In this embodiment, each set of the supporting legs 1 includes two left and right supporting legs 11, the two supporting legs 11 are provided with supporting leg grooves 111, two jacks 22 installed between the supporting legs 1 are respectively connected in one supporting leg groove 111, and the width of the cross beam 21 is smaller than or equal to the width of the supporting leg groove 111.
In this embodiment, the height adjusting device 2 is lifted and lowered in the range of the plane formed between the two legs 11.
In the present embodiment, the cart 100 includes the vehicle passage 200, and the height of the vehicle passage 200 becomes high or low when the height adjusting device 2 is operated, and the top and both sides of the cart 100 are respectively provided with the work platform 3.
The features and functions of the present utility model will be further understood from the following description.
In this embodiment, a height-adjustable tunnel excavation trolley 100 is disclosed, the trolley 100 includes a steel skeleton constituting a main frame, and a working platform 3 is provided on the top and both sides thereof for a worker to perform engineering operations thereon. Four groups of supporting legs 1 are formed by steel bones at four corner positions of the trolley 100, each steel bone is one supporting leg 11, each supporting leg 11 is provided with a supporting leg groove 111, a height adjusting device 2 is arranged between each group of supporting legs 1, the trolley 100 is integrally lifted through lifting of the height adjusting device 2, so that the relative height of a vehicle channel 200 is improved, and engineering vehicles such as a concrete mixing tank truck can pass through.
The specific structure of the height adjusting device 2 is shown in fig. 2, and the height adjusting device comprises a beam 21, wherein two jacks 22 are respectively arranged at two ends of the beam 21, the jacks 22 are arranged in supporting leg grooves 111 of supporting legs 11 at two sides, the extending ends of the jacks 22 are fixed in the supporting leg grooves 111, and two supporting shoes 23 are fixed at the central position of the bottom of the beam 21 to form a supporting base of the height adjusting device 2. The height adjusting device 2 can connect the jack 22 to the high-pressure end in a hydraulic or pneumatic mode, and the jack 22 is controlled by outputting hydraulic or pneumatic pressure through the high-pressure end.
In operation, the high-pressure end outputs pressure to the jack 22, the extending end of the jack 22 extends, and the supporting shoe 23 is supported on the bottom surface, so that the whole trolley 100 slowly rises when the extending end of the jack 22 extends, and the height of the vehicle channel 200 is increased, so that engineering vehicles such as a concrete mixer truck can pass through. The height adjusting device of the embodiment has a simple structure, can realize free lifting of the excavation trolley, and can freely adjust the height according to the height of the excavation trolley, so that the time consumption and potential safety hazards caused by the fact that the excavation trolley is transported out of a hole or a temporary support pad is used in the past are avoided. When the use is finished, the supporting shoe can be lifted, and the working state is quickly converted.
In summary, according to the utility model, the height adjusting device is arranged in the supporting leg of the trolley, so that when the height adjusting device works, the height of the vehicle channel of the trolley becomes high, and the engineering vehicles such as the concrete mixing tank truck can pass through conveniently. The height adjusting device has the advantages of simple structure, convenient installation and simple operation.
