Description

Technical Field

[0001] This utility model belongs to the field of tunnel construction technology, and specifically relates to a mobile device for electrical equipment inside a tunnel. Background Technology

[0002] During tunnel construction, different stages require different power supplies. Power equipment such as transformers may need to be moved closer to the work face to reduce line losses. Alternatively, if geological conditions change during construction, the equipment location may need to be adjusted to ensure safety. There may also be changes in the construction plan, requiring a relocation of the equipment. In addition, tunnel construction is usually carried out in sections, and each work face may require an independent power supply. Therefore, it is necessary to move power equipment such as transformers to adapt to the power needs of different sections.

[0003] Moving electrical equipment such as transformers inside tunnels usually requires the use of flatcars or trailers to save manpower and facilitate movement.

[0004] In the prior art, Chinese utility model patent document with authorization announcement number CN213892690U discloses a telescopic freight trailer for use in tunnels. One end of the towing frame is connected to the towing vehicle body, and the lower side of the other end is equipped with a steering wheel, and the upper side is connected to the first cargo platform through a rotating component. The upper side of the follower wheel is connected to the second cargo platform through a fixed frame. Under the traction of the towing vehicle body and the action of the rotating component, the first cargo platform can rotate with the curve of the tunnel. However, when traveling in a straight line, if the road surface is uneven or there is a lateral force, the rotating component may rotate freely, and the trailer may sway left and right, affecting stability and even causing the equipment to collide with the tunnel wall or other obstacles.

[0005] Therefore, it is necessary to design a tunnel-mounted electrical equipment moving device that can not only move with the tunnel curve but also move stably along a straight line to solve the current technical problems. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, this utility model provides a tunnel power equipment moving device that can not only move with the tunnel curve, but also move stably along the straight line.

[0007] The technical solution of this utility model is as follows: a mobile device for power equipment in a tunnel, including a support frame, a traction frame at the front end of the support frame, a crossbar fixedly installed on one end of the traction frame near the support frame, a rear wheel set and a front wheel set on both sides of the support frame, the front wheel set having an axle seat, a traveling wheel rotatably mounted on the axle seat, a connecting plate fixedly mounted on the top of the axle seat, the top of the connecting plate corresponding to the middle of the traveling wheel being rotatably connected to the bottom of the support frame, the end of the connecting plate opposite to the axle seat being rotatably connected to the end of the crossbar, and a locking mechanism provided on the support frame; the locking mechanism is used to lock or release the front wheel set and the support frame when the front wheel set is in the same direction of travel as the rear wheel set.

[0008] Furthermore, the locking mechanism has a locking support plate fixedly installed at the front end of the support frame, and a locking bolt is vertically installed on the locking support plate; a groove plate is fixedly installed on the top of the connecting plate, and the end of the crossbar is rotatably installed between the connecting plate and the groove plate. A through hole matching the locking bolt is opened on the top of the groove plate. When the front wheel assembly and the rear wheel assembly travel in the same direction, the through hole corresponds to the locking bolt.

[0009] Furthermore, an internally threaded support cylinder is fixedly provided on the top of the locking support plate, and the locking bolt is threadedly assembled inside the internally threaded support cylinder.

[0010] Furthermore, the rear end of the support frame is provided with a rear support mechanism, which is either abutted against or separated from the ground.

[0011] Furthermore, the rear support mechanism has a lower support, with lower connecting rods hinged to both ends of the lower support, an upper connecting rod hinged to the upper end of the lower connecting rod, the upper end of the upper connecting rod hinged to the bottom of the support frame, a screw rotatably mounted on the top of the lower support, the screw threadedly connected to the support frame, and a handle mounted on the top end of the screw.

[0012] Furthermore, a rear support plate is fixedly installed at the bottom of the lower support, and a rubber plate is fixedly installed at the bottom of the rear support plate.

[0013] Furthermore, the support frame is a rectangular frame structure welded from H-beams, and the interior of the support frame has horizontal and vertical braces.

[0014] The beneficial effects of this utility model are:

[0015] (1) In this utility model, when moving through a tunnel curve or turning, the locking mechanism releases the front wheel assembly. Under the traction of the traction frame, the crossbar drives the connecting plate and the axle seat to rotate, and the axle seat drives the walking wheel to rotate, so that it can move with the tunnel curve or turning.

[0016] (2) When it is necessary to move in a straight line inside the tunnel, the front wheel group and the rear wheel group should travel in the same direction. Then, the front wheel group and the support frame should be locked by the locking mechanism to fix the travel direction of the front wheel group and the rear wheel group and improve their stability when traveling in a straight line.

Under the traction of the traction frame 2, the crossbar 3 drives the connecting plate 53 and the axle seat 52 to rotate. The axle seat 52 drives the traveling wheel 51 to rotate, which can move along the curve or turning in the tunnel. When it is necessary to move in a straight line inside the tunnel, the front wheel assembly 5 and the rear wheel assembly 6 travel in the same direction. Then, the locking mechanism 42 locks the front wheel assembly 5 to the support frame 1, so that the travel direction of the front wheel assembly 5 and the rear wheel assembly 6 is fixed, thereby improving their stability when traveling in a straight line.

[0024] In some embodiments, the locking mechanism 4 has a locking support plate 41 fixedly disposed at the front end of the support frame 1, and a locking bolt 42 is vertically disposed on the locking support plate 41; a groove plate 54 is fixedly disposed on the top of the connecting plate 53, and the end of the crossbar 2 is rotatably disposed between the connecting plate 53 and the groove plate 54. A through hole matching the locking bolt 52 is opened on the top of the groove plate 54. When the front wheel assembly 5 and the rear wheel assembly 6 travel in the same direction, the through hole corresponds to the locking bolt 42; when the device moves in a curved path inside the tunnel, the locking bolt 42 is pulled out from the through hole, and the traveling wheel 51 can rotate under the traction of the traction frame 2 to achieve curved movement inside the tunnel; when straight movement is required, the front wheel assembly 5 and the rear wheel assembly 6 travel in the same direction, and the through hole on the groove plate 54 corresponds to the locking bolt 52.

A screw 75 is rotatably provided on the top of the lower support 72. The screw 75 is threadedly connected to the support frame 1. A handle 76 is provided at the top of the screw 75. By rotating the screw 75 through the handle 76, the threaded structure between the screw 75 and the support frame 1 can drive the lower support 72 to move up and down, thereby supporting or separating the lower support 72 on the ground. The upper connecting rod 74 and the lower connecting rod 73 can stabilize the lower support 72.

[0028] In some embodiments, a rear support plate 71 is fixedly provided at the bottom of the lower support 72.
