Description

Technical Field

[0001] The utility model relates to the technical field of electric pallet trucks, and specifically relates to a foot for an electric pallet truck. Background Technique

[0002] In the processes of logistics transportation, warehousing, etc., electric pallet trucks are often used to transfer goods. The electric pallet truck can lift the feet and the goods on the feet by means of a lifting system, and then transfer the goods in a motor-driven manner. Due to the characteristics of simple operation, stable running, safe and reliable, labor-saving, time-saving, and high efficiency, the electric pallet truck is widely used in goods handling.

[0003] The fork spacing of pallet trucks on the market is usually fixed. In order to facilitate the insertion of the forks under the pallet, the spacing between the forks is usually not too large. When using such pallet trucks to transfer some goods with too wide a volume, a support plate is needed. For example, in the patent application with the authorization publication number CN216584042U, the authorization publication date of May 24, 2022, and the name "An Electric Pallet Truck with Expandable Forks", when handling wider and larger goods, the first support arm can be rotated first to make the angle between the first support arm and the fork be degrees, and the locking bolt is screwed to make its lower end abut against the top of the first support arm to fix the angle between the first support arm and the fork; at this time, the second end of the first support arm and the second support arm have disengaged from the recessed part of the fork, and then the second support arm is rotated to make the second support arm abut against the positioning baffle, and the angle between the first support arm and the second support arm is locked by a buckle. At this time, the second support arm is parallel to the fork, and the free end of the second support arm and the free end of the fork face the same direction; finally, the extension arm is pulled out to an appropriate length as needed; in the actual use process of the above device, the position of the second support arm needs to be manually adjusted until the second support arm is in a suitable position, which increases the operation burden of the staff and is relatively inconvenient to operate.

[0004] Therefore, we propose a foot for an electric pallet truck to solve the problems raised above. Content of the Utility Model

[0005] 1. Technical problems to be solved by the utility model:

[0006] The purpose of the utility model is to provide a foot for an electric pallet truck to solve the problems in the current market proposed in the above background technique.

[0007] 2. Technical solution:

[0008] To achieve the above object, the utility model provides the following technical solutions: A fork of an electric pallet truck, including a bottom plate fixedly installed on the frame of the electric pallet truck and a mounting bracket installed on the lifting mechanism of the frame of the electric pallet truck. Two fork bodies are symmetrically installed front and back above the bottom plate on the mounting bracket, and a reinforcing plate is installed on the side of the fork body away from the center of the mounting bracket. An adjusting component is installed inside the mounting bracket, and the adjusting component is used to adjust the distance between the two reinforcing plates;

[0009] A rack plate is fixedly installed on the upper inner wall of the fork body, a releasing member is installed on the side of the rack plate, and a ratchet pawl member is installed at the end of the releasing member. The releasing member is used to drive the displacement of the ratchet pawl member;

[0010] A first rotating rod and a second rotating rod are respectively rotatably installed below the fork body and above the bottom plate, and a ratchet disc is fixedly sleeved in the middle of the rotating shaft of the first rotating rod.

[0011] Furthermore, a movable rod is fixedly installed on the side of the reinforcing plate close to the center of the mounting bracket, and the movable rod is fitted and slidably installed inside the mounting bracket. A connecting plate is rotatably installed on the side of the reinforcing plate close to the fork body, and one end of the connecting plate is rotatably installed on the side of the nearer fork body.

[0012] Through the above technical solution, the supporting ability of the reinforcing plate can be improved under the action of the connecting plate.

[0013] Furthermore, the adjusting component includes a worm and a bidirectional threaded rod installed inside the mounting bracket through bearings. A worm gear is fixedly installed in the middle of the bidirectional threaded rod, and the worm gear and the worm form a meshing structure. The bidirectional threaded rod and the movable rod form a threaded connection.

[0014] Through the above technical solution, when the worm rotates, the bidirectional threaded rod can be driven to rotate by the meshing action between the worm and the worm gear.

[0015] Furthermore, the first rotating rod is slidably sleeved outside the second rotating rod, and rubber bumps are evenly installed on the outside of the second rotating rod.

[0016] Through the above technical solution, when the fork body moves upward, the ratchet disc can be driven to rotate by the fitting action between the first rotating rod and the second rotating rod.

[0017] Furthermore, the ratchet pawl member and the ratchet disc form a ratchet assembly.

[0018] Through the above technical solution, the ratchet disc rotates unidirectionally under the action of the ratchet pawl member.

[0019] Further, the releasing member includes an electric push rod fixedly installed on the shelf board, a substrate is fixed to the output end of the electric push rod, and the pawl member is installed on the substrate.

[0020] Through the above technical solution, after the electric push rod is started, it can drive the pawl member away from the ratchet disc, and then the ratchet disc can rotate in the reverse direction.

[0021] 3. Beneficial effects:

[0022] Adopting the technical solution provided by the present utility model, compared with the prior art, the electric pallet truck foot of the present utility model adjusts the distance between the two reinforcing plates through the adjusting assembly, thereby facilitating the adjustment of the bearing surface according to the actual situation and expanding the practical performance. The specific content is as follows:

[0023] (1) When it is necessary to carry items with a relatively wide volume, start the motor at the lower end of the worm. The motor drives the worm to rotate. After the worm rotates, it drives the bidirectional threaded rod to rotate by means of the meshing action with the worm gear. When the bidirectional threaded rod rotates, the movable rod sleeved on the outer side of the bidirectional threaded rod is subjected to a driving force, and by means of the fitting action with the mounting frame, it moves inside the mounting frame, thereby driving the reinforcing plate to displace, expanding the bearing surface, improving the bearing capacity, and at the same time, the reinforcing plate further improves the strength by means of the connecting plate between the reinforcing plate and the foot body. Then, drive the foot body and the reinforcing plate to extend into the bottom of the tray for carrying;

[0024] (2) When the lifting mechanism on the electric pallet truck drives the foot body to move upward, the first rotating rod will slide on the outer side of the second rotating rod. During the sliding process, the first rotating rod and the second rotating rod will rotate synchronously, and the ratchet disc installed on the rotating shaft of the first rotating rod will rotate accordingly. When it moves up to a certain height, by means of the cooperation between the pawl member and the ratchet disc, the reverse rotation of the ratchet disc is avoided, thereby realizing the supporting effect on the end of the foot body far away from the mounting frame and improving the handling stability. Then, when unloading, start the electric push rod to drive the pawl member away from the ratchet disc. Description of the drawings

[0034] Please refer to Figures 1-4, A fork of an electric pallet truck, including a bottom plate 1 fixedly installed on the frame of the electric pallet truck and a mounting bracket 2 installed on the lifting mechanism of the frame of the electric pallet truck. Two fork bodies 3 are symmetrically installed before and after above the bottom plate 1 on the mounting bracket 2, and a reinforcing plate 4 is installed on the side of the fork body 3 away from the center of the mounting bracket 2. An adjusting component 5 is installed inside the mounting bracket 2, and the adjusting component 5 is used to adjust the distance between the two reinforcing plates 4; A movable rod 41 is fixedly installed on the side of the reinforcing plate 4 close to the center of the mounting bracket 2, and the movable rod 41 is fitted and slidably installed inside the mounting bracket 2. A connecting plate 42 is rotatably installed on the side of the reinforcing plate 4 close to the fork body 3, and one end of the connecting plate 42 is rotatably installed on the side of the closer fork body 3; The adjusting component 5 includes a worm 51 and a bidirectional threaded rod 52 installed inside the mounting bracket 2 by bearings. A worm gear 53 is fixedly installed in the middle of the bidirectional threaded rod 52, and the worm gear 53 and the worm 51 form a meshing structure. The bidirectional threaded rod 52 and the movable rod 41 form a threaded connection;

[0035] When it is necessary to carry items with a relatively wide volume, start the motor at the lower end of the worm 51. The motor drives the worm 51 to rotate. After the worm 51 rotates, it drives the bidirectional threaded rod 52 to rotate by the meshing action with the worm gear 53. When the bidirectional threaded rod 52 rotates, the movable rod 41 sleeved on the outside of the bidirectional threaded rod 52 is subjected to a driving force. The movable rod 41 realizes movement inside the mounting bracket 2 by the fitting action with the mounting bracket 2, thereby driving the reinforcing plate 4 to displace, expanding the bearing surface, improving the bearing capacity. At the same time, the reinforcing plate 4 further improves the strength by the connecting plate 42 between the reinforcing plate 4 and the fork body 3, and then drives the fork body 3 and the reinforcing plate 4 to extend into the bottom of the pallet for carrying;

[0036] A frame plate 8 is fixedly installed on the upper inner wall of the fork body 3, a releasing member 9 is installed on the side of the frame plate 8, and a pawl member 10 is installed at the end of the releasing member 9. The releasing member 9 is used to drive the pawl member 10 to displace; A first rotating rod 6 and a second rotating rod 7 are respectively rotatably installed below the fork body 3 and above the bottom plate 1, and a ratchet disc 11 is fixedly sleeved in the middle of the rotating shaft of the first rotating rod 6; The first rotating rod 6 is slidably sleeved on the outside of the second rotating rod 7, and rubber bumps are evenly installed on the outside of the second rotating rod 7; The pawl member 10 and the ratchet disc 11 form a ratchet assembly; The releasing member 9 includes an electric push rod 91 fixedly installed on the frame plate 8, a substrate 92 is fixed at the output end of the electric push rod 91, and the pawl member 10 is installed on the substrate 92;

[0037] When the lifting mechanism on the electric pallet truck drives the foot body 3 to move upward, the first rotating rod 6 will slide outside the second rotating rod 7. During the sliding process, the first rotating rod 6 and the second rotating rod 7 will rotate synchronously, and the ratchet disc 11 installed on the rotating shaft of the first rotating rod 6 will rotate accordingly. When it moves up to a certain height, the cooperation between the pawl member 10 and the ratchet disc 11 is utilized to prevent the ratchet disc 11 from rotating in the reverse direction, thereby realizing the supporting effect on the end of the foot body 3 far away from the mounting bracket 2 and improving the handling stability. Subsequently, when unloading, the electric push rod 91 is activated to drive the pawl member 10 away from the ratchet disc 11.

[0038] Working principle: When using the feet of this electric pallet truck, as Figures 1-4 shown, when it is necessary to handle items with a relatively wide volume, the motor at the lower end of the worm 51 is started, and the adjustment assembly 5 is used to drive the two reinforcing plates 4 to displace, expanding the bearing surface and improving the bearing capacity. At the same time, the reinforcing plates 4 further improve the strength through the connecting plates 42 between the reinforcing plates 4 and the foot body 3. Then, the foot body 3 and the reinforcing plates 4 are driven to extend into the bottom of the pallet for handling. And when the lifting mechanism on the electric pallet truck drives the foot body 3 to move upward, the ratchet disc 11 rotates by means of the sliding action between the first rotating rod 6 and the second rotating rod 7. When it moves up to a certain height, the cooperation between the pawl member 10 and the ratchet disc 11 is utilized to prevent the ratchet disc 11 from rotating in the reverse direction, thereby realizing the supporting effect on the end of the foot body 3 far away from the mounting bracket 2 and improving the handling stability. Subsequently, when unloading, the electric push rod 91 is activated to drive the pawl member 10 away from the ratchet disc 11.
