[0048] The top of the movable seat 1 is provided with limiting plates 21 on two opposite sides. The binding belt 22 is connected to the two limiting plates 21 .

[0049] As a preferred embodiment, the limiting plate 21 is arc-shaped. The inner arc surfaces of the two limiting plates 21 are arranged opposite to each other.

[0050] The splicing beam is fixedly connected to the moving seat. A socket channel is provided at one end of the other moving seat. The splicing beam is slidably connected to the socket channel at one end of the other moving seat. A support plate is fixedly connected to one end of the moving seat 1. By setting a locking structure, the vehicle body can be easily adjusted, the stability of the equipment is increased, and the difficulty of operating the equipment is reduced.

[0051] A second locking hole is provided at one end of the support plate, and a locking tongue is slidably connected to the inner wall of the second locking hole at one end of the support plate. The locking tongue is provided to facilitate fixing of the vehicle body, increase the stability of the equipment, and facilitate positioning of the vehicle body.

[0052] One end of the lock tongue is fixedly connected with a lifting spring, and one end of the lifting spring away from the lock tongue is fixedly connected with the support plate.

[0053] By arranging a lifting spring, when in use, the lifting spring generates elastic force to push the lock tongue to slide, thereby increasing the stability of the device.

[0054] One end of the other movable seat is fixedly connected to a comb plate, and a first locking hole is opened on the surface of the comb plate. The lock tongue is engaged with the first locking hole on the surface of the comb plate. By setting the comb plate, it is convenient to cooperate with the lock tongue to position the vehicle body, which increases the stability of the equipment and facilitates use.

[0055] The surface of the movable seat is provided with a binding structure, which includes a limit plate, which is fixedly connected to the movable seat. There are two limit plates, which are arranged in a mirror-symmetrical manner. A mounting plate is fixedly connected to the surface of the limit plate, and an axial hole is opened on the surface of the mounting plate. The inner wall of the axial hole on the surface of the mounting plate is slidably connected with a shaft rod.

[0056] By setting up the binding structure, it is convenient to position the shield machine and move the equipment, thus improving the safety of the equipment.

[0057] A rotating rod is fixedly connected to one side of the limit plate, a strap is fixedly connected to the surface of the rotating rod, and a rod sleeve is fixedly connected to the other end of the strap. By providing the rod sleeve, it is convenient to store and position the strap, which increases the usability of the equipment and facilitates operation.

[0058] Specifically, the rod sleeve is detachably sleeved on the shaft rod. In this embodiment, by providing the shaft rod, it is convenient to position the rod sleeve, which increases the usability of the device, facilitates the restraint of the shield machine, and increases the stability of the device.

[0059] Working principle: By setting up a locking structure, when in use, pull the other moving seat to unfold the vehicle body. When the length of the vehicle body reaches a suitable position, release the lock tongue, the lock tongue loses its restraint, and the lifting spring generates elastic force to push one end of the lock tongue to be inserted into the first lock hole of the comb plate to complete the positioning and locking.

[0060] Press the lock tongue downward to disengage the comb plate, and then move the moving seat to adjust the length of the vehicle body again.

[0061] By setting up the locking structure, it is convenient to adjust the length of the vehicle body, which increases the stability of the equipment, reduces the difficulty of operating the equipment, increases the safety of the equipment, and facilitates the adjustment of the vehicle body according to the environment.

[0062] After the length of the vehicle body is adjusted to the right position, the worm is rotated to drive the screw to rotate and drive the connecting block to move upward, so that the push plate pushes the two wing plates to open and extend to the outside of the through hole of the lock tongue, thereby limiting the lock tongue from separating from the comb plate.

[0063] When the binding structure is in use, the trolley of the shield machine is placed on the body, and the binding straps are pulled to bind the trolley of the shield machine. Then the shaft rod is pressed and inserted into the rod sleeve. At this time, the binding straps are locked, which increases the stability of the equipment. The shaft rod is pulled out of the rod sleeve, and the binding straps can be removed. By setting up the binding structure, it is easy to fix the shield machine, which reduces the possibility of the shield machine falling and increases the safety of the equipment.

[0064] The lateral translation device of the shield machine trolley of the present invention realizes the splicing of two moving seats to form a length-adjustable vehicle body to carry the shield machine trolley by plugging the plug-in beams of the two moving seats into the socket channel, thereby being able to adapt to the translation of various types of trolleys, and then locking the two moving seats through a locking structure, and locking the shield machine trolley on the two moving seats through a binding structure.
