Problems solved by technology

The automatic container lock pin disassembly system of the invention can effectively improve the efficiency of container loading and unloading, realize fully automated operation, break the automation bottleneck of container loading and unloading, and protect the personal safety of workers. However, the automatic disassembly system requires relatively large operations. space, and the overall system occupies a large area and investment, which is suitable for large ports and has poor adaptability
[0005] The Chinese invention patent application with the application number 201911134577.0 discloses a container transport vehicle and its rotary lock mechanism. The rotary lock mechanism includes a lock mechanism and a lock control mechanism. The lock mechanism includes a lock seat, a socket, a lock and a driving mechanism. parts; the lock seat is fixed on the frame of the container transport vehicle, and the lock seat is sleeved on the upper part of the outer circumference of the lock head; the connecting seat is sleeved on the lower part of the lock head outer circumference, and the connecting seat can rotate relative to the lock head seat The lock head is fixedly connected with the connecting seat, and is rotatably connected with the lock head seat, and the lock head exceeds the lock head seat upward; The lock head is opened and closed; the lock head control mechanism is fixed on the frame of the container transport vehicle. By automatically detecting whether there is a container on the frame, the driving part is automatically controlled to drive the lock head to rotate to switch the lock head to open and close. The semi-trailer frame Usually used for long-distance transportation, affected by vibration for a long time, the automatic control drive parts are easily damaged
[0006] What is especially important is that among the various methods that people are researching at this stage, the locks are operated separately, which takes a long time and cannot achieve unified operation. Once unified operation is realized, the usage of power source can be greatly reduced, which is beneficial to Automated operations provide the basis

Embodiment 1

[0037] like Figure 1-3As shown, a semi-trailer comprises a semi-trailer frame 1, a box body 3 is installed on the semi-trailer frame 1, a traction frame 2 is arranged at the front end of the semi-trailer frame, a traction pin 21 is installed on the traction frame, and the semi-trailer frame 1 A plurality of locks 4 for locking the box body 3 are installed on it, the lock 4 includes a shaft sleeve 402, the shaft sleeve 402 is equipped with a rotating shaft, the upper end of the rotating shaft extends to the outside of the shaft sleeve 402, and a lock head 404 is welded and fixed, and the lower end of the rotating shaft extends A drive handle 403 is fixed to the outside of the shaft sleeve 402, thereby forming the basic structure of the container lock, and then locked with the locking hole at the lower end of the box body 3. In this embodiment, a mounting plate is welded and fixed outside the shaft sleeve 402 401, and further bolt or welding fixed connection with the semi-trail...

Embodiment 2

[0043] like Figure 4 As shown, a semi-trailer is different from Embodiment 1 in that the locking driving cable 5 and the reset driving cable 8 are combined into one cable, and the first end of the cable is connected to the locking driving rod 6, and the pulling The second end of the cable is connected to the reset driving pull rod 9, correspondingly, a driving lever can be fixed on the driving handle 403, and only one ring is needed, and the reset limit lever 14 is installed on the axle sleeve 402, and the reset limit The included angle between the position lever 14 and the locking drive lever 10 is 90°, only through the locking positioning stopper 11, the locking and reset action can be limited, and the lock positioning device and the reset positioning device can be realized. Double function, simpler structure.

Embodiment 3

[0045] like Figure 5 As shown, a kind of semi-trailer, different from Embodiment 2, is that the driving handle 403 is externally processed with a toothed ring, and the rack 15 matched with the toothed ring is installed on the cable, and the driving handle 403 is driven to rotate through the toothed rack 15, and the transmission High precision, a chute 17 for guiding the rack 15 is installed on the semi-trailer frame 1, thereby ensuring that the rack 15 moves along a straight line, and a locking limit rod 16 is also installed on the driving handle 403 to lock The included angle between the stop bar 16 and the reset stop bar 14 is 90°, and the locking positioning stopper 11 is fixed between the reset stop bar 14 and the locking stop bar 16 on the axle sleeve 402 to realize locking. The double function of the stop positioning device and the reset positioning device can realize the limit of the two working states of the limit of the lock.

Abstract

The invention relates to the field of special-purpose semi-trailers, in particular to a semi-trailer for carrying boxes. A centralized drive device is arranged between the drive handles of each lock. The centralized drive device includes a locking drive device and a reset drive device. The locking drive The device includes a locking driving part, which is connected with a locking driving cable, and the locking driving cable is connected to the driving handle, and each lock is connected by the locking driving cable, and then multiple locks can be controlled by one power source. Two locks operate at the same time to achieve simultaneous locking and quickly lock the box body. The reset drive device includes a reset drive part connected to a reset drive cable connected to the drive handle. When the box needs to be removed When the body is assembled, the power source drives the reset and drives the cable to drive the lock to reset, and the box can be hoisted and removed, reducing personnel intervention and providing a basis for automatic loading and unloading.

Description

technical field [0001] The invention relates to the field of special-purpose semi-trailers, in particular to a semi-trailer for carrying boxes. Background technique [0002] Semi-trailer is the main way of road freight at present. According to the classification, semi-trailer mainly includes folding dump semi-trailer, warehouse-type semi-trailer, box-type semi-trailer, tank-type semi-trailer, and van-type semi-trailer mainly includes semi-trailer The frame is used to install the box on the semi-trailer frame, thereby forming a moving box space, carrying goods, or forming a functional box. [0003] In order to ensure the stability of the connection between the box body and the semi-trailer frame, the box body and the semi-trailer are generally locked and fixed by locks. The locks are usually container locks. The existing container locks mainly include shaft sleeves. A rotating shaft is installed, the upper end of the rotating shaft extends to the outside of the shaft sleeve ...
