Abstract
Description
Technical Field
[0001] This utility model relates to the field of semi-trailer technology, specifically to a vehicle-mounted moving top-mounted device. Background Technology
[0002] Currently, in the busy logistics, transportation, and warehousing industry, large and medium-sized trucks are loaded with a great deal of goods. When a truck arrives at its destination and begins unloading, the truck doors are opened and unloading begins. During the unloading process, as more and more goods are unloaded, the cargo piles up, causing the truck wheels to be submerged in cargo. This is especially true for side-tipping bulk material transport trucks, where the unloaded bulk material piles up and blocks the truck's path. After unloading, the truck is difficult to drive out, and the cargo around the truck wheels must be cleared again, which is time-consuming and labor-intensive.
[0003] The prior art patent CN212172038U discloses a vehicle-mounted displacement top lifting device, including a chain, a shaped handle, and a pin ring. The vehicle frame is provided with two parallel I-beams, and the lower end of the I-beams is provided with a lower wing plate. The upper end of the shaped handle is provided with a locking hole. The upper end of the chain is fixed to the side of the vehicle frame, and the lower end of the chain is detachably connected to the upper end of the shaped handle via a pin ring. The lower end of the pin ring is hinged to the displacement top. The shaped handle is provided with a slot for the lower wing plate to be inserted. By removing the pin ring and pushing the shaped handle outward, the displacement top can be lowered, realizing the lateral movement of the vehicle frame. This effectively avoids the impact of cleaning the goods around the vehicle after unloading the truck. However, this flexible connection method, which connects the cylinder of the shifting top to the semi-trailer's underbody beam at one end of a chain and the other end of the chain to the semi-trailer's underbody beam, is prone to causing the shifting top to sway during semi-trailer operation. This swaying is especially severe when the road is rough and bumpy, which reduces the service life of the connecting parts.
[0004] In response to the above problems, this utility model proposes a technical solution that differs from the prior art. Utility Model Content
[0005] The technical problem to be solved by this utility model is that the existing flexible connection locking device has a short service life and complex structure due to the influence of rough roads during long-term use. The present invention provides a vehicle-mounted displacement top-mounted device.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A vehicle-mounted displacement top-mounting device includes a displacement top hinged to a vehicle frame crossbeam. I-beams are fixedly installed at both ends of the vehicle frame crossbeam. A lower wing plate is provided at the lower end of the I-beam. The device also includes an irregularly shaped handle hinged to the side wall of the displacement top through a connector. A first slot for engaging the lower wing plate is provided on the irregularly shaped handle. A second slot is provided on the upper surface of the lower wing plate. The irregularly shaped handle is engaged with the second slot through a locking device.
[0007] Furthermore, the side wall of the first slot of the irregular handle has a first blind hole at the corresponding position of the second slot, and the side wall of the irregular handle has a second blind hole that is connected to the first blind hole. Both the first blind hole and the second blind hole extend upward by a predetermined length.
[0008] Furthermore, the locking device includes a first locking bar and a second locking bar that are slidably connected in the first blind hole and the second blind hole, respectively. The end of the first locking bar is a wedge-shaped surface, and the second locking bar has a hole with a wedge-shaped cross-section at a position corresponding to the first locking bar. The second locking bar moves upward by the interaction between the wedge-shaped surface of the first locking bar and the side wall of the hole.
[0009] Furthermore, a compression spring is connected between the second locking bar and the bottom of the first blind hole, and the deformation of the compression spring causes the second locking bar to move downward under force.
[0010] Furthermore, the upper surface of the irregular handle has a groove corresponding to the position of the first blind hole. The bottom of the groove extends downward to connect with the first blind hole. It also includes a locking block. The locking block is detachably embedded in the groove and the bottom of the locking block abuts against the bottom wall of the groove. The locking block and the first locking bar are elastically connected by a compression spring. The deformation of the compression spring causes the second locking bar to move downward under force.
[0011] The beneficial effects of this utility model are: this utility model has a first slot for engaging the lower wing plate on the irregularly shaped handle, and a second slot on the upper surface of the lower wing plate. The irregularly shaped handle is engaged with the second slot by a locking device. The structure is simple and easy to operate. Attached Figure Description

[0017] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0018] This application discloses a vehicle-mounted displacement ceiling device. Example
[0019] Reference Figures 1 to 3 A vehicle-mounted displacement top 2 lifting device includes a displacement top 2 hinged to a vehicle frame crossbeam 1. I-beam beams 3 are fixedly installed at both ends of the vehicle frame crossbeam 1. A lower wing plate 4 is provided at the lower end of the I-beam beam 3. The device also includes an irregularly shaped handle 5 hinged to the side wall of the displacement top 2 via a connector. The irregularly shaped handle 5 has a first slot 51 for engaging with the lower wing plate 4. A second slot is provided on the upper surface of the lower wing plate 4. The irregularly shaped handle 5 is engaged with the second slot 52 via a locking device.
[0020] Reference Figures 1 to 3 The irregular handle 5 has a first blind hole on the side wall of the first slot 51 corresponding to the second slot 52, and a second blind hole 54 on the side wall of the irregular handle 5 connected to the first blind hole 53. The first blind hole 53 and the second blind hole 54 both extend upward by a preset length. The locking device 6 includes a first locking strip 61 and a second locking strip 62 that are slidably connected in the first blind hole 53 and the second blind hole 54, respectively. The end of the first locking strip 61 is a wedge-shaped surface, and the second locking strip 62 has a wedge-shaped hole 63 on the side wall corresponding to the first locking strip 61. The second locking strip 62 moves upward by interacting with the wedge-shaped surface of the first locking strip 61 and the side wall of the hole. The service life of the device can be extended by replacing the first locking strip 61 and the second locking strip 62.
[0021] Reference Figures 1 to 3 A compression spring 64 is connected between the second locking bar 62 and the bottom of the first blind hole 53. The compression spring 64 deforms to make the second locking bar 62 move downward under force. By setting the compression spring 64, the second locking bar 62 can always be in contact with the bottom of the second locking groove 52, thereby improving the stability of the device.
[0022] The implementation principle of the vehicle-mounted displacement top 2 lifting device in this application embodiment is as follows: a first slot 51 for engaging the lower wing plate 4 is opened on the irregular handle 5, and a second slot 52 is opened on the upper end face of the lower wing plate 4. The irregular handle 5 is engaged with the second slot 52 by a locking device 6. The locking device includes a replaceable first locking strip 61 and a second locking strip 62 that are slidably connected in the first blind hole and the second blind hole, which improves the overall service life of the device, has a simple structure, and is easy to operate. Example
[0023] Reference Figure 1 and Figure 4 The upper surface of the irregular handle 5 has a groove 7 corresponding to the position of the first blind hole 53. The bottom of the groove 7 extends downward to connect with the first blind hole 53. It also includes a locking block 8. The locking block 8 is detachably embedded in the groove 7 and the bottom of the locking block 8 abuts against the bottom wall of the groove 7. The locking block 8 and the first locking strip 61 are elastically connected by a compression spring 64. The deformation of the compression spring 64 causes the second locking strip 62 to move downward under force. By installing and removing the locking block 8, the operator can quickly disassemble or replace the first locking strip 61, thereby improving work efficiency and the service life of the overall device.
[0024] The above embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
