Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a lifting feeding device for a trailer. Background Art

[0002] A trailer is a vehicle that can be towed or connected to the back of a motor vehicle for the transportation of cargo or other items. Trailers usually do not have their own power system, but rely on the tractor for power. They can be simple truck trailers for transporting goods, or specially designed trailers for transporting ships, large equipment or other special cargo. The design and purpose of trailers vary, and different types of trailers can be selected as needed to meet different transportation needs.

[0003] Existing trailers are usually loaded manually, but manual loading requires operators to perform repetitive actions, and long-term operation can easily lead to fatigue and physical discomfort. In addition, manual loading is relatively slow and inefficient, and there are safety risks such as operational errors and accidental injuries during manual loading, especially when handling heavy or large cargoes. Accidents are more likely to occur. Utility Model Content

[0004] The utility model aims to provide a lifting loading device for a trailer which can reduce manual labor, improve loading efficiency and reduce accident risks.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A lifting loading device for a trailer comprises a base plate, a rotating seat is rotatably installed on the upper surface of the base plate, a rotating mechanism capable of driving the rotating seat to rotate is arranged on the outer surface of the base plate, an L-shaped plate is installed on the upper surface of the rotating seat, mounting grooves are arranged on both side plates of the L-shaped plate, threaded rods A are rotatably connected between the upper and lower side walls of the two mounting grooves, and the threads of the two threaded rods A are arranged oppositely, two limit rods are connected between the upper and lower side walls of the mounting groove, and the two limit rods are symmetrically arranged on both sides of the threaded rod A, driving blocks are installed on the outer surfaces of the two limit rods and the threaded rod A, loading plates A and loading plates B are respectively installed on the outer surfaces of the two driving blocks, and a driving mechanism capable of simultaneously driving the two threaded rods A to rotate is arranged on the top of the L-shaped plate.

[0007] It can be seen that, through the setting of the driving mechanism, the loading plate A and the loading plate B can be driven to rise and fall, so that the materials can be lifted to a high place, which is convenient for the staff on the vehicle to take the materials and put them in the vehicle, thereby reducing labor, improving loading efficiency, and reducing safety hazards. In addition, through the setting of the rotating mechanism, the L-shaped plate can be driven to rotate. When the loading plate A or the loading plate B is located at the bottom, it can be horizontally arranged next to the trailer to reduce the distance between the device and the trailer. After the loading plate A or the loading plate B lifts the material to a height, it is rotated to the inner side of the trailer through the rotating mechanism, so it is convenient for the staff on the vehicle to take the materials, avoiding the risk of the staff extending their bodies to the outside of the trailer to take the materials, and generating the risk of falling, which is safer. Moreover, since the threads of the two threaded rods A are arranged in opposite directions, under the drive of the driving mechanism, the loading plate A and the loading plate B can be respectively located at the top and bottom positions. While the staff on the vehicle are taking the materials, the staff at the bottom can discharge the materials, thereby ensuring the continuity of the feeding and improving the feeding efficiency.

[0008] Furthermore, the rotating mechanism includes a motor A installed on the outer surface of the base plate, a driving gear A is installed at the end of the output shaft of the motor A, a gear ring is sleeved on the outer surface of the rotating seat, and the driving gear A is meshed and connected with the gear ring.

[0009] Through the meshing relationship between the driving gear A and the gear ring, when the motor A is started, the rotating seat can be driven to rotate.

[0010] Furthermore, the driving mechanism includes a motor B installed at the inner corner of the L-shaped plate, and a driving gear B is installed at the end of the output shaft of the motor B. The upper ends of the two threaded rods A both penetrate into the upper side of the L-shaped plate and are installed with driven gears, and the two driven gears are both meshed and connected with the driving gear B.

[0011] When motor B is started, it can drive driving gear B to rotate. Due to the meshing relationship between driving gear B and driven gear, it can drive two limit rods to rotate in the same direction at the same time. And because the threads of the two limit rods are oppositely arranged, it can drive loading plate A and loading plate B to rise and fall in opposite directions.

[0012] Furthermore, a protective cover is installed on the top of the L-shaped plate, and the protective cover is arranged on the outside of the driving gear B and the driven gear.

[0013] By setting the protective cover, the driving gear B and the driven gear can be protected, reducing the influence of dust and other substances on them, and improving the performance and life.

[0014] Furthermore, an oblique support rod is installed at the inner corner of the L-shaped plate, and the end of the oblique support rod is connected to the rotating seat.

[0015] By providing the diagonal bracing rods, the structural strength of the L-shaped plate can be improved, thereby improving the load-bearing capacity of the carrier plates A and B.

[0016] Furthermore, universal wheels are installed at the four corners of the bottom of the base plate, and a handrail is installed on the side of the upper surface of the base plate away from the L-shaped plate.

[0017] The arrangement of the universal wheels and the armrests makes it easy to push the device to move, thereby improving the flexibility of use.

[0018] Furthermore, two fixing blocks are installed on the outer surfaces of both sides of the bottom plate, and a threaded rod B penetrates through and is threadedly connected to the inside of the fixing block. A supporting block is installed at the bottom of the threaded rod B, and a handwheel is installed on the top of the threaded rod B.

[0019] When the device is in use, the hand wheel can be rotated to drive the support block to descend and support it on the ground, and the universal wheel can be lifted, so that the device can be kept stable during the loading process, thereby improving the safety of the loading operation.

[0020] Furthermore, enclosures are installed on three sides of the upper surfaces of the loading plate A and the loading plate B.

[0021] By setting up enclosures, materials can be shielded and the risk of falling can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The utility model is described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-4 As shown, a lifting loading device for a trailer includes a bottom plate 100, a rotating seat 101 is rotatably mounted on the upper surface of the bottom plate 100, a rotating mechanism 200 capable of driving the rotating seat 101 to rotate is arranged on the outer surface of the bottom plate 100, an L-shaped plate 102 is mounted on the upper surface of the rotating seat 101, mounting grooves 103 are arranged on both side plates of the L-shaped plate 102, threaded rods A104 are rotatably connected between the upper and lower side walls of the two mounting grooves 103, and the two threaded rods A104 The threads are arranged oppositely, and two limit rods 105 are connected between the upper and lower side walls of the installation groove 103, and the two limit rods 105 are symmetrically arranged on both sides of the threaded rod A104. The outer surfaces of the two limit rods 105 and the threaded rod A104 are installed with driving blocks 106, and the outer surfaces of the two driving blocks 106 are respectively installed with loading plates A107 and loading plates B108. The top of the L-shaped plate 102 is provided with a driving mechanism 300 that can drive the two threaded rods A104 to rotate at the same time.

[0029] When in use, the device is moved to the side of the trailer, and then the materials are loaded into the loading plate B108. Subsequently, the two threaded rods A104 are driven to rotate by the driving mechanism 300. Since the threads of the two threaded rods A104 are arranged oppositely, the loading plate A107 drops in the process of driving the loading plate B108 to rise. When the loading plate B108 rises to the top, the rotating seat 101 is driven to rotate 90 degrees by the rotating mechanism 200. At this time, the loading plate B108 rotates to the inside of the trailer, which is convenient for the staff in the car to take the materials, and avoids the risk of the staff extending their bodies to the outside of the trailer to take the materials, which may cause the risk of falling. The loading plate A107 is arranged horizontally next to the trailer. While the staff on the vehicle are taking materials, the staff under the vehicle can load materials into the loading plate A107. When the materials in the loading plate B108 are taken out, the rotating mechanism 200 drives the rotating seat 101 to rotate 90 degrees again, and rotates the loading plate B108 to the outside of the trailer. Then, the driving mechanism 300 drives the loading plate A107 to rise and the loading plate B108 to fall. Then, the rotating mechanism 200 drives the rotating seat 101 to rotate 180 degrees, and drives the loading plate A107 to rotate to the inside of the trailer, thereby realizing continuous loading and improving loading efficiency.

[0030] Specifically, the rotating mechanism 200 includes a motor A201 installed on the outer surface of the base plate 100, a driving gear A202 is installed at the end of the output shaft of the motor A201, a gear ring 203 is sleeved on the outer surface of the rotating seat 101, and the driving gear A202 is meshingly connected with the gear ring 203. Through the meshing relationship between the driving gear A202 and the gear ring 203, when the motor A201 is started, it can drive the rotating seat 101 to rotate.

[0031] Specifically, the driving mechanism 300 includes a motor B301 installed at the inner corner of the L-shaped plate 102, and a driving gear B302 is installed at the end of the output shaft of the motor B301. The upper ends of the two threaded rods A104 pass through the upper side of the L-shaped plate 102 and are installed with driven gears 303, and the two driven gears 303 are meshingly connected with the driving gear B302. When the motor B301 is started, it can drive the driving gear B302 to rotate. Due to the meshing relationship between the driving gear B302 and the driven gear 303, it can drive the two limit rods 105 to rotate in the same direction at the same time. Since the threads of the two limit rods 105 are oppositely arranged, they can drive the loading plate A107 and the loading plate B108 to rise and fall in opposite directions.

[0032] Specifically, a protective cover 400 is installed on the top of the L-shaped plate 102, and the protective cover 400 is arranged on the outside of the driving gear B302 and the driven gear 303. Through the setting of the protective cover 400, the driving gear B302 and the driven gear 303 can be protected to reduce their influence by dust and other substances, thereby improving their performance and life.

[0033] Specifically, an oblique support rod 500 is installed at the inner corner of the L-shaped plate 102, and the end of the oblique support rod 500 is connected to the rotating seat 101. By setting the oblique support rod 500, the structural strength of the L-shaped plate 102 can be improved, thereby improving the load-bearing capacity of the carrier plate A107 and the carrier plate B108.

[0034] Specifically, universal wheels 600 are installed at the four corners of the bottom of the base plate 100, and an armrest 601 is installed on the side of the upper surface of the base plate 100 away from the L-shaped plate 102. The arrangement of the universal wheels 600 and the armrest 601 facilitates the movement of the device and improves the flexibility of use.

[0035] Specifically, two fixing blocks 700 are installed on the outer surfaces of both sides of the base plate 100, and a threaded rod B701 passes through and is threadedly connected to the interior of the fixing block 700, a supporting block 702 is installed at the bottom of the threaded rod B701, and a handwheel 703 is installed at the top of the threaded rod B701. When the device is in use, the handwheel 703 can be rotated to drive the supporting block 702 to descend and support it on the ground, thereby lifting the universal wheel 600, so that the device can remain stable during the loading process and the safety of the loading operation is improved.

[0036] Specifically, enclosures 800 are installed on three sides of the upper surfaces of the loading plates A107 and B108. By setting the enclosures 800, the materials can be shielded to reduce the risk of falling.
