[0002] In industrial production, the drive head is a key component that drives the vibrating screen to perform reciprocating motion. It often needs to be inspected and maintained because of the harsh working environment, high-intensity operations and frequent impact loads, which may lead to fastener damage, unbalanced counterweights and other problems.

[0003] In the existing drive head design, the counterweight is generally made of thick steel plates and is fan-shaped, in order to ensure the overall dynamic balance of the vibrating screen. During maintenance, the counterweight of the replaced drive head needs to be removed and installed on the new drive head. However, this design does not take into account convenient disassembly and assembly methods, so when replacing the drive head, maintenance personnel must manually flip the entire drive head, use gravity to let the counterweight slide off by itself, and then manually install the new counterweight with difficulty. In addition, due to the special installation position of the counterweight, it is closed on all sides and can only be installed from the top. The installation space is limited, making it impossible to easily position and guide it.

[0004] Therefore, a drive head counterweight disassembly and assembly tool is needed to at least solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the embodiments of the present application is to provide a drive head counterweight disassembly and assembly tool to solve the current problem of time-consuming, labor-intensive and difficult positioning process when disassembling and assembling the counterweight on the drive head.

[0023] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0024] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0025] As the core component of the vibrating screen for reciprocating motion, the drive head often needs to be regularly inspected and repaired due to its harsh working environment and high force, which involves the replacement of the counterweight. Each piece of the existing drive head counterweight is heavy. The counterweight does not have a built-in threaded hole or other structure that is easy to disassemble and assemble. The conventional replacement method is that multiple people work together to flip the entire drive head 180°, use gravity to make the counterweight fall off, and then take it out piece by piece and install it on the new drive head. However, due to the irregular shape of the drive head and the uneven mass distribution, the flipping process requires multiple people to exert force at the same time, which poses a great safety risk. At the same time, the process of flipping the drive head and manually installing the counterweight is time-consuming. Since the counterweight installation position is closed on all sides and there are two long vertically installed screws below, the counterweight can only be installed from directly above, and the two holes must be accurately aligned with the screws, but the screw length is not enough to provide sufficient guidance, resulting in difficulty in the installation and positioning of the counterweight, and the success rate is not high. After the counterweight installation fails, it is necessary to flip the drive head again and use other tools to remove the stuck counterweight, which not only increases the labor intensity of the maintenance personnel, but also delays the maintenance time and reduces work efficiency. Therefore, the drive head counterweight disassembly and assembly tool provided in the present application can simplify the disassembly and assembly process, is highly safe, and saves time and effort.

[0026] Example 1

[0027] The embodiment of the present application provides a drive head counterweight disassembly and assembly tool, such as Figure 1 and Figure 2 As shown, it includes: a first connecting member 1, which is used to be firmly connected to a part to be disassembled or installed; a second connecting member 2, the second connecting member 2 has a first surface 201, and the first connecting member 1 is connected to the first surface 201; an abutting top portion 3, the abutting top portion 3 is perpendicular to the first surface 201 and is rotatably connected to the second connecting member 2, and the first end 301 of the abutting top portion 3 is located on a side of the second connecting member 2 having the first surface 201; wherein the first end 301 can move forward or backward toward the second surface 101 of the first connecting member 1 facing away from the first surface 201 through the rotation of the abutting top portion 3 relative to the second connecting member 2.

[0028] The first connecting member 1 can achieve a stable connection with the part to be disassembled or installed. The first connecting member 1 can be a jaw, a slot, a clamp or other structure that can adapt to different parts to ensure that the target part will not loosen or shift during the operation, thereby ensuring the stability and safety of the disassembly and assembly operation. The second connecting member 2 is the basic bearing structure of the drive head counterweight disassembly and assembly tool. The first connecting member 1 and the abutment top 3 are both arranged on the second connecting member 2. The first end 301 of the abutment top 3 can approach or move away from the second surface 101 of the first connecting member 1 during the rotation process, so that the position of its first end 301 can be changed by rotation according to the needs of the disassembly and assembly steps.

[0029] When a secure connection with a part is required, the first end 301 of the abutting top 3 will rotate away from the second surface 101 of the first connecting member 1 to form a lifting effect, so that the first connecting member 1 and the part can be smoothly docked; and in the disassembly stage, it is only necessary to drive the abutting top 3 to rotate forward to move the first end 301 toward the second surface 101, thereby pressing the part downward and causing the part to be disconnected from the first connecting member 1.

[0030] The drive head counterweight disassembly and assembly tool provided in the embodiment of the present application can achieve a quick and stable connection with the part to be disassembled or installed through the first connecting member 1. Through the coordinated work of the abutment top 3 and the first connecting member 1, a directional force can be provided during the disassembly and assembly process to ensure that the parts are subjected to a stable thrust during disassembly, thereby effectively overcoming the cumbersome and difficult problems in the existing drive head counterweight disassembly and assembly process, significantly improving the efficiency of the disassembly and assembly operation, reducing labor intensity, and ensuring operation safety.

[0031] In some embodiments, the first end 301 is non-contacting and disposed close to the first connecting member 1 , and an end surface of the first end 301 is parallel to the second surface 101 .

[0032] The abutting top portion 3 does not contact the first connecting member 1 but maintains a certain distance therefrom, but is still in a position where it can quickly approach and act on the part to avoid interference between the abutting top portion 3 and the first connecting member 1 to ensure normal use of the tool.

[0033] Since the end surface of the first end 301 is parallel to the second surface 101 of the first connecting member 1, when the abutting top 3 contacts the part, it can ensure that the direction of the force is perpendicular to the surface of the part, which is conducive to achieving precise positioning and uniform force, reducing the possibility of misoperation, thereby improving work efficiency.

[0034] In some embodiments, the drive head counterweight disassembly and assembly tool further includes: a gripping portion 4 , the gripping portion 4 is connected to a third surface 202 of the second connecting member 2 facing away from the first surface 201 .

[0035] like Figure 1 and Figure 2 As shown, the gripping portion 4 is connected to the third surface 202 of the second connecting member 2 facing away from the first surface 201, and can be composed of a handle, a grip or other structure that is convenient for the operator to hold and control, so as to provide an operator with a position to directly contact and control the drive head counterweight disassembly tool. Through the gripping portion 4, the user can control the movement of the first connecting member 1 and the abutting top portion 3 more stably and effortlessly, and better control the angle and direction of the drive head counterweight disassembly tool, especially for situations where operations need to be performed in a limited space or at a specific angle, providing more freedom and flexibility.

[0036] In some embodiments, the gripping portion 4 is U-shaped, and an open side of the gripping portion 4 faces the third surface 202 .

[0037] Since the U-shaped opening faces the third surface 202, the user can easily grasp the gripping portion 4 by wrapping his fingers around it, which is convenient for operating and controlling the tool from multiple directions with one hand or both hands. The U-shaped gripping portion 4 is designed in accordance with ergonomic principles, providing a more stable gripping effect, and avoiding accidental injuries or damage to the parts to be disassembled due to slipping of the tool during the disassembly and assembly process.

[0038] The gripping portion 4 is made of a rod material with a circular cross section, which is bent into a U-shape, and the two ends of the gripping portion 4 can be fixedly connected to the second connecting member 2 by welding. Specifically, the second connecting member 2 is provided with a pair of mounting through holes matching the diameter of the gripping portion 4, and the positions of the two through holes are adapted to the distance between the two ends of the gripping portion 4, ensuring that the two ends of the gripping portion 4 can be inserted therein, and the gripping portion 4 is permanently and firmly connected to the second connecting member 2 by welding, which can not only ensure the strength and stability of the overall structure, but also ensure that the gripping portion 4 will not become loose or fail due to force during the disassembly and assembly process.

[0039] Alternatively, the gripping portion 4 may be threadedly connected to the second connecting member 2. Specifically, first threaded holes with internal threads may be provided at both ends of the gripping portion 4, and second threaded holes matching the internal threads are provided at corresponding positions of the second connecting member 2. Bolts are used to penetrate the first threaded holes and the second threaded holes to connect and fix the two, so that the gripping portion 4 can be easily assembled and disassembled with the second connecting member 2.

[0040] In some embodiments, Figure 1 and Figure 2 As shown, the second connecting member 2 is a plate structure, the abutting top 3 is a rod structure, the second connecting member 2 is provided with a first through hole in a direction perpendicular to the first surface 201, and the abutting top 3 passes through the first through hole and is threadedly connected to the second connecting member 2.

[0041] The top part 3 adopts a rod-shaped structure, and the second connecting member 2 is a plate structure, but the specific shape of the second connecting member 2 is not limited. Through the threaded connection, the rotational motion of the top part 3 can be converted into a linear motion along the axis of the thread. When the operator rotates the top part 3, due to the effect of the thread, the top part 3 can move up and down along the thread in the first through hole of the second connecting member 2, thereby achieving precise telescopic adjustment. The drive head counterweight disassembly and assembly tool provided in the embodiment of the present application can adjust the length of the top part 3 extending out of the second connecting member 2 according to actual disassembly and assembly needs through a simple rotation action to achieve the disassembly and assembly effect, which greatly improves the efficiency of the disassembly and assembly operation.

[0042] In some embodiments, the second end 302 of the abutting portion 3 opposite to the first end 301 is located on the third surface 202 side, and the second end 302 is provided with a protrusion.

[0043] The abutment top portion 3 adopts a rod-shaped structure, including a first end 301 and a second end 302 opposite to each other, and the second end 302 is located on the side of the third surface 202 of the second connecting member 2 facing away from the first surface 201, that is, on the same side as the gripping portion 4. A protrusion is configured at the second end 302, and the protrusion can have a specific shape and size, such as a common ball head, a conical head or a flat head. By providing a protrusion at the second end 302 of the abutment top portion 3, the operator can more conveniently hold and drive the abutment top portion 3 to rotate, which greatly improves the convenience and comfort of manual operation. By rotating the abutment top portion 3, the rotational motion is converted into linear motion by means of a threaded connection, so that the drive head counterweight disassembly tool can achieve precise telescopic adjustment.

[0044] In some embodiments, the thread length of the abutment portion 3 is not less than the thickness of the gripping portion 4 plus the first connecting member 1 .

[0045] Specifically, the abutment portion 3 may be a round-wing butterfly bolt, the head of which has a butterfly-shaped profile, which expands the lateral force area in contact with the hand, so that the operator can more easily apply torque during manual twisting, thereby improving work efficiency. The thread length of the round-wing butterfly bolt ensures that the bolt has sufficient travel to perform telescopic adjustment during twisting, that is, the thread length is not less than the thickness of the gripping portion 4 plus the first connecting member 1, ensuring that within the maximum telescopic range, the abutment portion 3 can maintain effective contact and force with the parts to be disassembled.

[0046] In some embodiments, the second connecting member 2 is provided with a second through hole in a direction perpendicular to the first surface 201, and the first connecting member 1 is provided with a third through hole in a direction perpendicular to the second surface 101; it also includes: a third connecting member 5, the third connecting member 5 passes through the second through hole and the third through hole in sequence, and the first connecting member 1 and the second connecting member 2 are threadedly connected through the third connecting member 5.

[0047] The second through hole and the third through hole are both provided with internal threads, and the third connecting member 5 can be a bolt. The threaded connection makes the connection between the first connecting member 1 and the second connecting member 2 very stable, and will not easily loosen even when a large torque or pulling force is applied for disassembly and assembly, thereby ensuring the safety and stability of the disassembly and assembly process. If the first connecting member 1 or the second connecting member 2 needs to be replaced or maintained, the two can be separated by simply unscrewing the third connecting member 5, which is simple and quick to operate, reducing maintenance costs and time.

[0048] In some embodiments, Figure 1 and Figure 2As shown, the first connecting members 1 are a pair, the pair of first connecting members 1 are arranged along the length direction of the second connecting member 2 , and the pair of first connecting members 1 are symmetrically distributed on the first surface 201 relative to the center of the second connecting member 2 .

[0049] A pair of first connecting members 1 can fix the parts to be disassembled or installed from two points at the same time, just like two points determine a straight line, which can distribute the load-bearing capacity more evenly, and the symmetrical layout allows the drive head counterweight disassembly tool to act more evenly on the object to be disassembled when in use, avoiding excessive force on one side, and improving the stability and safety of disassembly. Two independent first connecting members 1 can work independently or in coordination, and can be adjusted individually or operated synchronously according to different disassembly requirements, which improves the flexibility and adaptability of the drive head counterweight disassembly tool.

[0050] In some embodiments, the abutting portion 3 is a pair, and the pair of abutting portions 3 are disposed on both sides of a pair of first connecting members 1 along the length direction of the second connecting member 2 .

[0051] Specifically, on the same axis of the second connecting member 2, there is an abutment portion 3 on each side adjacent to a first connecting member 1. The symmetrically arranged abutment portion 3 structure can ensure that the drive head counterweight disassembly tool applies a balanced force to the target component from both sides during operation, thereby improving the stability and accuracy of the disassembly operation. The cooperation of the two pairs of abutment portions 3 and the first connecting member 1 can operate on two corresponding parts of the part at the same time, significantly improving the disassembly speed and work efficiency.

[0052] In some embodiments, Figure 1 and Figure 2 As shown, the U-shaped gripping portion 4 is arranged along the length direction of the second connecting member 2, and the center line of the gripping portion 4 is collinear with the center line of the second connecting member 2. Since the center lines of the gripping portion 4 and the second connecting member 2 are collinear, gravity can be evenly distributed along the center line of the tool, reducing fatigue caused by long-term use of the tool.

[0053] In some embodiments, the two ends of the U-shaped gripping portion 4 are respectively coaxially arranged with a pair of first connecting members 1. Since the gripping portion 4 is arranged along the length direction of the second connecting member 2 and is respectively coaxially arranged with a pair of first connecting members 1, the overall tool structure is more compact and suitable for disassembly and assembly operations in an environment with limited space.

[0054] In some embodiments, the first connecting member 1 is a magnet.

[0055] The first connection member 1 of the magnet can be automatically adsorbed on the metal part of the part to be disassembled or installed, without manual continuous gripping, which significantly improves the convenience and work efficiency of operation, especially in narrow spaces or environments with poor visibility, the magnetic connection can reduce the difficulty of operation. The magnetic connection has a wide range of applicability, not only can it be used for metal parts, but also can be extended to non-metal parts by adding magnetic accessories, etc., which increases the versatility and adaptability of the drive head counterweight disassembly and assembly tool.

[0056] Specifically, the magnet can be a hollow cylindrical structure, the outer layer of which is wrapped with a stainless steel metal shell to protect the powerful magnet inside and increase the durability and corrosion resistance of the magnet. A conical countersunk hole is provided at the bottom of the magnet, and the third connecting member 5 can be a cross slot countersunk screw. The inner diameter of the center circle of the magnet is slightly larger than the diameter of the cross slot countersunk screw, so that the magnet can accommodate and adsorb the cross slot countersunk screw, but will not hinder the normal rotation and tightening of the screw. Finally, the magnet is fastened to the screw hole on the bottom surface of the second connecting member 2 or the end of the gripping portion 4 by a cross slot countersunk screw to ensure that the magnet can be firmly fixed in the specified position, and use its magnetic function to adsorb or assist in disassembly and assembly.

[0057] The use principle of the drive head counterweight disassembly and assembly tool provided in the embodiment of the present application is illustrated by an example:

[0058] When removing the counterweight of the drive head, the magnetism on the first connecting member 1 can be used to firmly adsorb it on the surface of the counterweight, ensuring that the counterweight will not accidentally slip off during the disassembly process. The operator can pull the counterweight vertically upward by holding the U-shaped or other adaptively designed gripping portion 4, and lift the counterweight from the drive head until it is completely out of contact with the drive head. After the counterweight is lifted, the first end 301 can apply a directional thrust to the counterweight by rotating the abutting top portion 3 to release the adsorption state between the first connecting member 1 and the counterweight, and finally separate the counterweight from the first connecting member 1. When installing the counterweight of the drive head, first use the first connecting member 1 to adsorb the counterweight, align the counterweight with the installation position of the drive head, hold the gripping portion 4 and slowly lower the drive head counterweight disassembly tool, and then adjust the relative position of the first connecting member 1 and the counterweight by rotating the abutting top portion 3 to completely separate it from the first connecting member 1. Finally, take out the drive head counterweight disassembly tool to complete the installation of the counterweight.

[0059] The drive head counterweight disassembly and assembly tool provided in the embodiment of the present application integrates multiple practical functions and humanized designs, simplifies the originally complicated counterweight disassembly and assembly process, improves work efficiency, and reduces labor intensity.

[0060] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
