Description

Technical Field

[0001] This utility model relates to the technical field of monorail transport equipment, specifically a portable pole for attaching and detaching a monorail chain. Background Technology

[0002] Using lifting chains to secure materials is a crucial operation for transport teams during lifting operations. By securing materials with lifting chains, it ensures that they will not shift or fall during transport, effectively preventing accidents or damage to lifting equipment caused by unstable materials. Furthermore, lifting chains evenly distribute the weight of the material, reducing the burden on both the material and the crane equipment, thus improving the safety and efficiency of lifting operations. This is especially important when dealing with irregularly shaped materials with uneven weight distribution, as it effectively prevents the material from tilting or falling during transport.

[0003] In actual operation, when using a monorail crane to lift materials, it is usually necessary to pass the lifting chain under the material and secure it to ensure that the material is fixed before lifting operations can be carried out. However, due to the wide variety of materials underground and the very narrow space below the material after loading, it is very difficult to directly pass the lifting chain under the material. Operators usually need to extend the lifting chain under the material, but due to the irregular shape of the material, it is difficult to guide the lifting chain accurately and it is impossible to pass directly through the material to complete the securing. This makes manual operation extremely cumbersome and poses certain safety hazards. Due to the narrow working space, operators are prone to being squeezed or bumped when reaching out to operate the lifting chain. Utility Model Content

[0004] The purpose of this utility model is to provide a portable monorail lifting chain rod to solve the problem that due to the wide variety of materials underground and the very narrow space below the materials after loading, it is very difficult to directly pass the lifting chain through the materials. Operators usually need to extend the lifting chain under the materials, but due to the irregularity of the materials, it is difficult to guide the lifting chain accurately and it is impossible to directly pass through the materials to complete the binding. This makes manual operation extremely cumbersome and poses certain safety hazards. Due to the narrow working space, operators are prone to being squeezed or bumped when reaching out to operate the lifting chain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-rail hanging chain portable rod, comprising a shell, a connecting shell, a gear, a rack, and a collar. The shell is a rectangular hollow shell with an opening to the left. A rack is provided inside the shell and slides within it. An internal threaded hole is provided on the side of the rack near the opening end of the shell, and a fixing rod is screwed into the threaded hole. A collar is connected to the top of the fixing rod and is connected to a chain hook. A connecting shell is connected to the side of the shell away from the opening end, and a gear is connected inside the connecting shell. A connecting groove is provided on the shell corresponding to the position of the gear, and the gear meshes with the rack. A vertically erected connecting rod is provided on the connecting shell. The bottom end of the connecting rod passes through the connecting shell and connects to the input end of the gear. An adjusting handwheel is connected to the top end of the connecting rod. An auxiliary groove is provided at the top end of the shell, and an operating rod is provided on the side of the auxiliary groove away from the opening end. The operating rod is hinged to the shell and has a positioning hole. An extension portion for hand gripping is also provided at the top end of the operating rod. The extension portion is perpendicular to the operating rod, and hand grips are connected to the front and rear ends of the extension portion, respectively.

[0006] Preferably, the length of the auxiliary groove is set to correspond to the length of the operating rod, and is used to accommodate the operating rod.

[0007] Preferably, the auxiliary groove has through holes on both the front and rear ends on the side away from the operating rod, and corresponding positioning holes are provided. A double-ended screw is inserted into the through hole, and the two ends are tightened by nuts to limit and fix the operating rod after rotation.

[0008] Preferably, the contact end between the connecting rod and the connecting shell is provided with a bearing seat to reduce friction.

[0009] Preferably, a handle is connected to the middle of the end of the operating lever away from the auxiliary slot.

[0010] Preferably, threaded holes are symmetrically provided on the left and right sides of the connecting groove, and a positioning screw is connected to the connecting shell at the position corresponding to the threaded hole. The positioning screw is screwed into the threaded hole to connect the connecting shell to the outer shell, and at the same time facilitates installation and disassembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By designing an outer casing and installing a guide rack inside, along with a gear on one side of the casing connected to the operating handwheel via a connecting rod, the lifting chain is guided through materials. First, the casing is inserted under the material. Then, the operating handwheel is turned, causing the gear to rotate the rack. The rack guides the lifting chain through the material via the movement of a collar. Next, the operator connects the hook of the lifting chain to the collar and turns the operating handwheel again to retract the rack, completing the guiding operation of the lifting chain. Afterward, the lifting chain can be secured.

[0013] Furthermore, the operating lever is designed as a hand-grip component, which improves the overall stability of the equipment during operation. When the lifting chain needs to be pulled out for securing, the operating lever helps the operator to drag the device more easily, increasing control and comfort during operation. The design of the operating lever allows users to easily pull the chain, ensuring that the lifting chain can smoothly pass through materials.

[0014] When not in use, the operating lever can be rotated and stored in the auxiliary slot, saving space and improving portability. To ensure the stability of the operating lever in the stored state, the device also uses a double-ended screw for limiting and fixing, preventing the operating lever from loosening due to external force. In addition, the device is equipped with a carrying handle for easy carrying during movement and convenient transfer between different work locations.

[0015] This design not only improves operational efficiency and safety, but also reduces the labor intensity of operators during hoisting operations. Through an effective guidance and retraction mechanism, operators can accurately guide and secure the hoisting chain in confined spaces, significantly reducing safety risks during operations. At the same time, the optimized structure and convenient carrying method make this equipment more adaptable and convenient in different working environments. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1-4This utility model provides an embodiment of a single-rail lifting chain portable rod, including a shell 1, a connecting shell 2, a gear 3, a rack 4, and a collar 5. The shell 1 is a rectangular hollow shell with an opening to the left. The shell 1 is the main body of the entire device, serving to accommodate and support other components. The opening corresponds to the area below the material, allowing the internal rack 4 to extend. The height of the shell 1 is set to correspond to the gap below the material. The overall material is rigid, providing some support for the material and facilitating the dragging and lifting of the chain hook. The shell 1 contains the rack 4, which slides... Fitting into the outer casing 1, the rack 4 is a component that meshes with the gear 3. Driven by the gear 3, it slides along the outer casing 1, completing linear motion to pass under the material, thereby connecting to the lifting chain and dragging it through the material for lifting operations. The rack 4 has an internal threaded hole on the side near the opening of the outer casing 1, with a fixing rod screwed into the threaded hole. The fixing rod connects the rack 4 and the collar 5. The use of the external thread and the internal threaded hole facilitates maintenance and installation. The top of the fixing rod is connected to the collar 5, which connects to the hook of the lifting chain, allowing the hook of the lifting chain to be hung on... The collar 5 is used for dragging. The collar 5 is connected to the chain hook. A connecting shell 2 is connected to the side of the outer shell 1 away from the opening end. The connecting shell 2 fixes the gear 3 and provides support for the gear 3. It cooperates with the connecting groove of the outer shell 1 to ensure the precise meshing of the gear 3 and the rack 4. Through the stable connection structure, the connecting shell 2 ensures the stability of the gear 3 system and avoids deviation between the gear 3 and the rack 4. The gear 3 is connected inside the connecting shell 2. The gear 3 meshes with the rack 4. When the gear 3 is rotated, the rack 4 slides along the outer shell 1 through the action of the tooth surface of the gear 3. The outer shell 1 corresponds to the gear 3. A connecting groove is provided at the position, and gear 3 meshes with rack 4. A vertically erected connecting rod 6 is provided on the connecting housing 2. The function of connecting rod 6 is to transmit the operating force from the handwheel to gear 3, which plays a role in adjustment and control. At the same time, an adjusting handwheel is provided on its top for easy manual operation, thereby controlling the extension or retraction of rack 4. The bottom end of connecting rod 6 passes through the connecting housing 2 and connects to the input end of gear 3, and the top end is connected to the adjusting handwheel. An auxiliary groove is provided at the top of the housing 1. An operating rod 7 is provided on the side of the auxiliary groove away from the opening end. The length of the auxiliary groove is set to correspond to the length of the operating rod 7 to accommodate the operating rod 7.

[0026] The auxiliary slot accommodates the operating lever 7, reducing space occupation and facilitating portability. The operating lever 7 is hinged to the housing 1 and has positioning holes. Designed as a hand-gripable component, the operating lever 7 improves the overall stability of the equipment during operation. When the lifting chain needs to be pulled out for securing, the operating lever 7 helps the operator to drag the device more easily, increasing control and comfort during operation. The design of the operating lever 7 allows users to easily pull the chain, ensuring the lifting chain can smoothly pass through materials. The top of the operating lever 7 also has a hand-held extension, which is perpendicular to the operating lever 7, with hand-held handles connected to its front and rear ends. The auxiliary slot is located away from... The operating lever 7 has through holes on both its front and rear ends, corresponding to positioning holes. Double-ended screws 8 are inserted into these through holes, and both ends are tightened with nuts. These screws limit and fix the operating lever 7 after rotation. After folding and storing the operating lever 7 in the auxiliary slot, the double-ended screws 8 are inserted and then fixed in place, increasing stability during transport. A bearing seat is provided at the contact end between the connecting rod 6 and the connecting shell 2 to reduce friction. A carrying handle 9 is connected to the middle of the end of the operating lever 7 furthest from the auxiliary slot. The carrying handle 9 allows the operator to easily hold the entire device for movement or transport. This design increases the device's portability, making it particularly suitable for work environments requiring frequent movement.

[0027] In use, first, insert the outer casing 1 under the material, then turn the operating handwheel to make the gear 3 drive the rack 4 to rotate. The rack 4 guides the lifting chain through the material via the movement of the collar 5. Next, the operator connects the hook of the lifting chain to the collar 5, and turns the operating handwheel again to retract the rack 4, thus completing the guiding operation of the lifting chain. At this time, the lifting chain can be tied. When it is necessary to pull out the lifting chain for tying, the operating lever 7 can help the operator to drag the device more easily and enhance the control and comfort during operation. The design of the operating lever 7 allows the user to pull the outer casing 1 to ensure that the lifting chain passes smoothly through the material. When not in use, the operating lever 7 can be rotated and stored in the auxiliary slot. After inserting the double-ended screw 8, tighten the nut for limit fixation to prevent the operating lever 7 from loosening due to external force. Then, it is easy to carry during movement via the carrying handle 9, making it convenient to transfer between different work locations.

[0028] Example 2: Please refer to Figure 3 Based on Example 1, it also has the following structure:

[0029] The connecting groove has symmetrical threaded holes on both sides. The connecting shell 2 is connected to the corresponding threaded hole. The positioning screw is screwed into the threaded hole to connect the connecting shell 2 to the outer shell 1. It is also convenient for installation and disassembly. When the length of the outer shell 1 meets the overall width, the connecting shell 2 can be disassembled. After the connecting shell 2 is completely disassembled, the outer shell 1 is inserted under the material. At the same time, the operating rod 7 is rotated to pass the outer shell 1 through the material and connect it to the lifting chain hook. When the length of the outer shell 1 does not meet the requirements for passing through the material, the connecting shell 2 is connected. The gear 3 and the rack 4 mesh to drive the transmission, thereby increasing the overall length of use.
