Description

Technical Field

[0001] This utility model relates to the field of crane beam system brake plate installation technology, specifically a portable auxiliary installation tool for high-strength bolts of crane beam system brake plates. Background Technology

[0002] In industrial plant construction, crane beam systems are a crucial component. Among them, the brake plate, a key component ensuring crane operational stability, is critically important in its connection quality with the crane beam. Currently, crane beam brake plates are mostly installed using torque-shear type high-strength bolts. This connection method faces numerous challenges in actual bolt installation. Because crane beams are typically installed at high locations, construction workers must insert the high-strength bolts from bottom to top into the bolt holes of the brake plate and crane beam in a high-altitude working environment—an extremely difficult operation. To complete the installation, a construction platform often needs to be erected below the installation location. This not only consumes significant time and labor costs and extends the construction period, but also increases the safety risks for construction workers due to the platform's height; even a slight mistake could lead to an accident, thus affecting the entire construction schedule. Therefore, there is an urgent need for an innovative installation tool and method to solve these problems in the installation of high-strength bolts for crane beam brake plates. Utility Model Content

[0003] The present invention aims to solve the above problems and thus provide a portable auxiliary installation tool for high-strength bolts on the brake plate of a crane beam system.

[0004] The technical solution adopted by this utility model to solve the aforementioned problem is:

[0005] A portable auxiliary installation tool for high-strength bolts on a crane beam system brake plate includes a torque-shear type high-strength bolt to be installed and a traction rope. One end of the traction rope is located above the brake plate and connected to a fall arrestor ring. The other end of the traction rope passes through a bolt hole on the brake plate from top to bottom and is connected to a counterweight steel column. Fixed rings are provided at both ends of the counterweight steel column. The bottom end of the traction rope is tied to one of the fixed rings, and a binding rope is tied to the other fixed ring. The bottom end of the binding rope is connected to the end of the torque-shear type high-strength bolt to be installed, which has a quincunx head.

[0006] Furthermore, the diameter of the fall arrestor ring is larger than the diameter of the bolt hole connecting the brake plate and the crane beam system; this prevents the counterweight steel column and the traction rope from falling downwards during use.

[0007] Furthermore, the traction rope is made of iron wire to prevent it from breaking due to prolonged friction with the edge of the bolt hole.

[0008] Compared with the prior art, the present utility model adopting the above technical solution has the following outstanding features:

[0009] This utility model features a simple structure and low manufacturing cost. By cleverly incorporating traction ropes, counterweight steel columns, and binding ropes, it changes the previous operation mode of painstakingly inserting bolts from the bottom up. This allows construction workers to conveniently install high-strength bolts without the need for high-altitude construction platforms, significantly reducing time and labor costs and effectively accelerating construction progress. Simultaneously, it reduces the need for high-altitude platform construction, lowering the safety risks associated with working at heights and providing a safer working environment, thus reducing the possibility of accidents. Furthermore, the operation process of this utility model is simple and easy to master, making the installation of high-strength bolts more efficient and stable. Attached Figure Description

[0014] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0015] Referring to Figures 1-3, a portable auxiliary installation tool for high-strength bolts on a crane beam system brake plate includes a high-strength torque-shear bolt 2 to be installed and a traction rope 3. One end of the traction rope 3 is located above the brake plate 1 and connected to a fall arrestor ring 4. The other end of the traction rope 3 passes through the bolt hole 11 on the brake plate 1 from top to bottom and is connected to a counterweight steel column 5. The counterweight steel column 5 has fixing rings at both ends. The bottom end of the traction rope 3 is tied to one of the fixing rings, and a binding rope 6 is tied to the other fixing ring. The bottom end of the binding rope 6 is connected to the end of the high-strength torque-shear bolt 2 to be installed, which has a quincunx head.

[0016] The diameter of the fall arrestor ring 4 is larger than the diameter of the bolt hole 11 connecting the brake plate 1 and the crane beam system; this prevents the counterweight steel column 5 and the traction rope 3 from falling downwards during use.

[0017] Furthermore, the traction rope 3 is made of iron wire to prevent the traction rope 3 from being interrupted due to prolonged friction with the edge of the bolt hole 11.

[0018] The method for installing high-strength bolts using this utility model is as follows: The operator, positioned above the crane beam, passes the binding rope 6 and the counterweight steel column 5 sequentially through the bolt holes 11 of the crane beam and brake plate 1 from top to bottom. The ground-based operator ties the end of the binding rope 6 to the end of the high-strength torque-shear bolt 2 with the spline head, securing the binding rope 6 to the groove where the spline head of the high-strength torque-shear bolt 2 connects to the bolt rod. After securing, the operator above lifts the traction rope 3 upwards, causing the high-strength torque-shear bolt 2 to rise until the spline head end protrudes upwards through the bolt hole 11. Then, a U-shaped clamp 7 is used to clamp the threaded groove of the high-strength bolt 2 to prevent it from slipping downwards. The binding rope 6 is untied, the nut is screwed on, and then the U-shaped clamp 7 is removed. The nut is then tightened using a dedicated electric torque-shear wrench.

[0019] This utility model features a simple structure and low manufacturing cost. By cleverly incorporating traction ropes, counterweight steel columns, and binding ropes, it changes the previous operation mode of painstakingly inserting bolts from the bottom up. This allows construction workers to conveniently install high-strength bolts without the need for high-altitude construction platforms, significantly reducing time and labor costs and effectively accelerating construction progress. Simultaneously, it reduces the need for high-altitude platform construction, lowering the safety risks associated with working at heights and providing a safer working environment, thus reducing the possibility of accidents. Furthermore, the operation process of this utility model is simple and easy to master, making the installation of high-strength bolts more efficient and stable.

[0020] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
