Description

Technical Field

[0001] This utility model relates to the field of pipe transportation, and more specifically, to a counterbalance forklift tilting pipe clamp. Background Technology

[0002] During the delivery of PPR and PVC drainage pipes, forklift clamps are used to transfer the pipes from the racks to the trucks. However, existing clamps have some limitations. Due to the short distance between the upper arms and insufficient lifting distance, some pipes cannot fall into the truck under their own weight after the clamp arms are opened. This results in incomplete pipe transfer, requiring additional manual intervention or the addition of a pipe-pushing device to complete the transfer. This not only reduces transfer efficiency but also increases operating costs and labor intensity, making it difficult to meet the demand for efficient and automated pipe transfer.

[0003] How to invent a counterbalance forklift tilting clamp to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a counterbalanced forklift tilting pipe clamp, which aims to improve the problem that after the existing forklift clamp arm is opened, some pipes cannot fall into the freight vehicle by their own weight, requiring additional manual intervention or the addition of a pipe pushing device, thereby reducing transfer efficiency, increasing operating costs and labor intensity, and making it difficult to meet the needs of efficient and automated transfer.

[0005] This utility model is implemented as follows: a balance forklift tilting clamp includes a fork tooth connecting part for connecting with the fork teeth. A fork tooth slot corresponding to the fork teeth is opened on one side of the fork tooth connecting part. Fixed limiting structures are detachably connected to both sides of the fork tooth slot. A clamping rod mounting part is provided at the top of the fork tooth connecting part. A clamping rod is rotatably mounted on the clamping rod mounting part. One end of the clamping rod near the fork tooth connecting part is connected to an opening and closing drive component. Protruding plates are integrally provided on both sides of the inner outer wall of the clamping rod. One end of a push tube plate is rotatably connected between the two protruding plates.

A connecting member is rotatably sleeved on the other end of the connecting shaft. The other end of the connecting member is fixedly connected to one end of the piston rod of the push-out drive member. The push-out drive member is rotatably mounted on the outer wall of the other side of the fork tooth connecting part.

[0008] In a preferred embodiment of this utility model, the pusher plate has connecting posts integrally formed on both sides of one end between the two protruding plates. Guide grooves are formed on the opposite side surfaces of the two protruding plates. Each connecting post is slidably connected in the corresponding guide groove, and the width of the guide groove is the same as the diameter of the connecting post. A groove is formed at one end of the pusher plate. One end of an adjusting block is rotatably connected between the inner walls of the two sides of the groove. The other end of the adjusting block extends to the other side through an extension groove formed through the surface of the clamping rod and is fixedly connected to one end of the piston rod of the adjusting drive component. The adjusting drive component is fixedly installed on the outer wall of the clamping rod.

[0009] In a preferred embodiment of this utility model, the fixed limiting structure includes two connecting frames. The surface of the fork tooth connecting part is provided with slots corresponding to the connecting frames on both sides of the fork tooth slot. Each connecting frame has a through-hole on one side surface. A fastener is inserted into each of the mounting holes. One end of the fastener is threaded into a corresponding threaded hole.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figures 1 to 6 This utility model provides a technical solution: a balance forklift tilting clamp, including a fork tooth connecting part 1 for connecting with fork teeth 6. A fork tooth slot 101 corresponding to the fork teeth 6 is provided on one side of the fork tooth connecting part 1. Fixed limiting structures are detachably connected to both sides of the fork tooth slot 101. A clamping rod mounting part 102 is provided at the top of the fork tooth connecting part 1. A clamping rod 2 is rotatably mounted on the clamping rod mounting part 102. One end of the clamping rod 2 near the fork tooth connecting part 1 is connected to the opening and closing drive member 3. Protruding plates 202 are integrally provided on both sides of the inner outer wall of the clamping rod 2. One end of a push tube plate 203 is rotatably connected between the two protruding plates 202. The other end of the push tube plate 203 is connected to the push-out drive member 4 through an adapter.

[0018] The fork tooth connecting part 1 serves as the overall mounting base. One side of the fork tooth slot 101 engages with the front of the vertical portion of the fork tooth 6. The fixing and limiting structures on both sides of the slot abut against the rear of the fork tooth via fasteners, enhancing overall stability. The clamping rod mounting part 102 at the top of the fork tooth connecting part 1 is equipped with a stainless steel rotating shaft. The clamping rod 2 is rotatably connected via this shaft. Its end near the fork tooth connecting part 1 is hinged to the opening / closing drive component 3 (preferably a hydraulic cylinder, compatible with the forklift hydraulic system). When the drive component extends or retracts, it causes the clamping rod 2 to rotate, opening and closing. When closed, it clamps the pipe; when open, it releases the pipe. The protruding plates 202 inside the clamping rod 2 are connected to one end of the push plate 203 via a connecting structure. The other end of the push plate 203 is connected to the ejection drive component 4 (a similar hydraulic cylinder) via an adapter. When the drive component operates, it causes the push plate to rotate and eject any remaining pipe.

[0019] Please see Figure 5 and Figure 6 The clamping rod 2 is integrally provided with a driving component connecting part 201 at one end near the fork tooth connecting part 1. The driving component connecting part 201 is rotatably connected to one end of the piston rod of the opening and closing driving component 3 through a hinge structure. The other end of the opening and closing driving component 3 is rotatably connected to the outer wall of one side of the fork tooth connecting part 1 through a hinge structure.

[0020] One end of the clamping rod 2 near the fork tooth connecting part 1 is provided with a driving component connecting part 201 (a lug plate welded and fixed to the clamping rod), and the lug plate has a hinge hole; the piston rod end of the opening and closing driving component 3 (hydraulic cylinder) is hinged to the lug plate through a U-shaped hinge seat with a pin, and the other end of the driving component is hinged to the mounting lug plate on the outer wall of the fork tooth connecting part 1 through the same structure. When the piston rod retracts, the clamping rod rotates axially around the mounting part and opens outward to facilitate pipe installation; when the piston rod extends, the clamping rod closes inward to clamp the pipe.

[0021] Furthermore, the adapter includes a connecting shaft 204, which is fixedly connected to one end of the push tube plate 203. A connecting member 205 is rotatably sleeved on the other end of the connecting shaft 204. The other end of the connecting member 205 is fixedly connected to one end of the piston rod of the push-out drive member 4. The push-out drive member 4 is rotatably mounted on the outer wall of the other side of the fork tooth connecting part 1.

[0022] The connecting shaft 204 of the adapter is welded to one end surface of the push plate 203, and the connecting piece 205 (with a copper sleeve installed in the shaft hole to reduce friction) is rotatably sleeved on it. The other end of the connecting piece 205 is bolted to the piston rod of the push-out drive 4 (hydraulic cylinder). The cylinder body of the push-out drive 4 is mounted on the outer wall of the other side of the fork tooth connection part 1 through a hinge structure. When the piston rod retracts, it drives the connecting shaft 204 through the connecting piece 205, causing the push plate 203 to rotate around the connection between the protruding plates 202 (towards away from the fork teeth), contacting and pushing out the tube; when extended, the push plate returns to its original position without interfering with the action of the clamping rod.

[0023] Furthermore, the push plate 203 is integrally provided with connecting posts 208 on both sides of one end between the two protruding plates 202. The two protruding plates 202 are provided with guide grooves 209 on the opposite side surface. Each connecting post 208 is slidably connected in the corresponding guide groove 209, and the width of the guide groove 209 is the same as the diameter of the connecting post 208. One end of the push plate 203 is provided with a groove. One end of the adjusting block 206 is rotatably connected between the inner walls of the two sides of the groove. The other end of the adjusting block 206 extends to the other side through the extension groove 207 through the surface of the clamping rod 2 and is fixedly connected to one end of the piston rod of the adjusting drive component 5. The adjusting drive component 5 is fixedly installed on the outer wall of the clamping rod 2.

[0024] The push plate 203 has connecting posts 208 on both sides at one end, and a guide groove 209 (straight extension with the groove width matching the diameter of the connecting post 208) is opened on the opposite side of the protruding plate 202. The connecting post 208 slides along the groove to achieve guiding and limiting. An adjusting block 206 is connected to the groove at one end of the push plate 203 by a pin. The other end of the adjusting block 206 passes through the extension groove 207 of the clamping rod 2 and is bolted to the piston rod of the adjusting drive component 5 (small electric push rod). The drive component is fixed to the outer bracket of the clamping rod. When the drive component extends or retracts, the adjusting block 206 moves along the extension groove 207, causing the push plate 203 to slide along the guide groove 209 of the 208 through the connecting post, changing the overall position of the push plate 203 to expand the push-out area and eliminate the blind spot. During the adjustment process, the piston rod of the push-out drive component 4 moves in coordination.

[0025] Please refer to the figure. Figure 3 and Figure 4 The fixed limiting structure includes two connecting brackets 103. The surface of the fork tooth connecting part 1 is provided with slots corresponding to the connecting brackets 103 on both sides of the fork tooth slot 101. Each connecting bracket 103 has a through mounting hole 104 on one side surface. Each mounting hole 104 is fitted with a fastener 105. One end of the fastener 105 is threaded into the corresponding threaded hole 106. Each threaded hole 106 is opened on the inner wall of the corresponding slot. An abutment clamping mechanism is provided between the two connecting brackets 103.

[0026] Two connecting brackets 103 of the fixed limiting structure are inserted into the slots of the fork tooth connecting part 1. High-strength bolts are inserted into the assembly holes 104 of the connecting brackets, and the bolts are screwed into the threaded holes 106 on the inner wall of the slots. An abutment clamping mechanism is provided between the two connecting brackets 103 to further strengthen the connection.

[0027] Furthermore, the abutting clamping mechanism includes an anti-slip clamping rubber block 107 and a connecting beam 108. The anti-slip clamping rubber block 107 is integrally disposed between the two connecting frames 103. One side surface of the anti-slip clamping rubber block 107 is flush with one side surface of the two connecting frames 103 to form a complete plane. The connecting beam 108 is integrally disposed between the other side surface of the two connecting frames 103. A screw hole 109 is provided through the connecting beam 108. An adjusting screw 111 is threadedly connected to the screw hole 109. One end of the adjusting screw 111 is rotatably connected to one side surface of the connecting plate 112. Both ends of the other side surface of the connecting plate 112 are fixedly connected to abutting clamping heads 113. One end surface of each of the two abutting clamping heads 113 is in contact with one side surface of the anti-slip clamping rubber block 107.

[0028] The anti-slip clamping block 107 of the clamping mechanism is fixed between the two connecting frames 103, with one side surface flush with the surface of the connecting frame 103 and fitting against the rear side of the fork tooth 6. The connecting beam 108 on the other side of the connecting frame 103 has a screw hole 109, into which an adjusting screw 111 is screwed. One end of the screw is connected to the connecting plate 112 via a bearing, and the other side of the connecting plate 112 is provided with an abutment clamping head 113. Rotating the screw causes the connecting plate 112 to drive the clamping head to squeeze the block, deforming it to fit tightly against the fork tooth 6, thus cooperating with the slot for bidirectional clamping.

[0029] Furthermore, two limiting plates 114 are symmetrically arranged on one side surface of the connecting plate 112. Each limiting plate 114 is slidably connected in a corresponding limiting slot 110. The two limiting slots 110 are opened on both sides of the connecting beam 108.

[0030] A limiting plate 114 is symmetrically provided on one side of the connecting plate 112, and limiting slots 110 are opened on both sides of the connecting beam 108. The limiting plate 114 slides along the slots. When the adjusting screw 111 rotates, the limiting plate 114 restricts the rotation of the connecting plate 112, so that it only moves in a straight line, ensuring that the two clamping heads are subjected to uniform force.

[0031] Working principle: The fork tooth 1 is engaged with the front side of the fork tooth 6 through the fork tooth slot 101 of the fork tooth connecting part 1, and is fixed from the rear side by the connecting brackets 103 on both sides and the abutment clamping mechanism, so as to achieve a stable connection between the overall structure and the fork tooth 6. The clamping rod 2 is rotatably mounted on the fork tooth connecting part 1 through the clamping rod mounting part 102 at the top of the fork tooth connecting part 1. A drive member connecting part 201 is provided at one end near the fork tooth connecting part 1. This connecting part is hinged to the opening and closing drive member 3. When the piston rod of the opening and closing drive member 3 extends or retracts, it can drive the clamping rod 2 to rotate around the rotation axis to realize the opening and closing action. When closed, it can stably clamp PPR, PVC and other pipes, and when open, it facilitates the loading and releasing of pipes. After the pipes are transferred to the freight vehicle and the clamp 2 is opened, if there are any pipe residues, the push-out drive 4 drives the push-out plate 203 to rotate around its connection with the inner protruding plate 202 of the clamp 2 via the adapter, pushing the residual pipes outward. At the same time, the adjustment drive 5 can drive the adjustment block 206 to move in the extension groove 207 of the clamp 2, causing the push-out plate 203 to slide along the guide groove 209 of the protruding plate 202 via the connecting column 208, changing the position of the push-out plate 203 to expand the push-out range, ensuring that all pipes can fall into the freight vehicle, effectively solving the problem of residual pipes in traditional clamping.

[0032] It should be noted that the specific models and specifications of the opening and closing drive component 3, the pushing drive component 4, and the adjusting drive component 5 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0033] The power supply and operating principle of the opening / closing drive 3, the pushing drive 4, and the adjusting drive 5 are clear to those skilled in the art and will not be described in detail here.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
