Description

Technical Field

[0001] The utility model relates to the technical field of lifting operations, in particular to a steel wire rope anti-slip groove fixing device. Background Art

[0002] In construction operations, some simple lifting equipment is often used to lift construction materials, and these lifting equipment require the cooperation of fixed pulleys when in use. Ordinary fixed pulleys have a simple structure. During the lifting of goods, due to shaking, it is easy to have abnormal situations such as oblique lifting, transition hook return, bouncing, and swinging, which will cause the wire rope to deviate from the mixed wheel track. After the wire rope is out of the groove, if it is not discovered and handled in time, it is easy to cause the wire rope to break and move, resulting in a safety accident. At present, there are also some structures in the prior art to prevent the wire rope from being out of the groove. For example, patent document CN202221994229.8 provides a wire rope anti-slip groove device for a small pulley, which has the characteristics of convenient and quick loading and unloading, simple maintenance, etc., but the device is limited to small pulleys, and cannot be used for a combination structure of multiple pulleys, and its scope of use is limited. Utility Model Content

[0003] In order to overcome the disadvantages of the existing pulley that the steel wire rope is easily derailed, the technical problem to be solved by the utility model is to provide a simple and practical steel wire rope anti-derailment fixing device.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A wire rope anti-slip groove fixing device includes a base plate and two side plates arranged on the base plate, a pin shaft is provided between the two side plates, a guide wheel is rotatably provided on the pin shaft, a groove is provided on the circumferential wheel surface of the guide wheel, two ends of the guide wheel are close to the side plates at both ends, and the top of the side plate is higher than the top edge of the wire rope bypassing the guide wheel, and the base plate is provided with connecting bolts for fixing the base plate to an external mechanism.

[0006] Furthermore, the pin shafts include two and are arranged in parallel on the side plate in the vertical direction, the wheel surfaces of the guide wheels on the two pin shafts are close to each other, and the grooves on the wheel surfaces are aligned, and the top of the side plate is higher than the top edge of the wire rope that passes around the guide wheel on the upper pin shaft.

[0007] Furthermore, two guide wheels are connected to the pin shaft, and one end of the two guide wheels is close to each other, and the other end is close to the side plates at both ends respectively.

[0008] Furthermore, a stiffening plate is provided between the side of the side plate facing away from the guide wheel and the base plate.

[0009] Furthermore, the stiffening plates include two, and are respectively arranged between the two ends of the side plate and the base plate.

[0010] Furthermore, the connecting bolts include four, two of which are arranged at intervals at each end of the base plate, and the two connecting bolts are located between the two stiffening plates.

[0011] The beneficial effect of the utility model is that a fixed bracket is separately provided to install the guide wheel, so that the side plates on both sides of the guide wheel are close to the two sides of the guide wheel, and the top of the side plate is higher than the top edge of the wire rope bypassing the guide wheel, so that the side plate can be used to limit the wire rope on the guide wheel to avoid the situation where the wire rope falls out of the groove, thereby ensuring the stable operation of the lifting operation, reducing safety hazards and improving operation efficiency.

[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] It should be noted that if there are directional indication terms in the present invention, such as up, down, left, right, front, and back directions and orientation terms, they are for the purpose of facilitating the description of the relative position relationship between components, and are not for the absolute position of the related components or the position relationship between components. They are only used to explain the relative position relationship and movement of the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. If there are terms related to quantity in the present invention, such as "multiple", "multiple", "several", etc., they specifically refer to two or more.

[0018] like Figure 1 , Figure 2 As shown, the utility model wire rope anti-slip groove fixing device comprises a base plate 1 and two side plates 2 arranged on the base plate 1, a pin shaft 3 is arranged between the two side plates 2, a guide wheel 4 is rotatably arranged on the pin shaft 3, a groove is arranged on the circumferential wheel surface of the guide wheel 4, the two ends of the guide wheel 4 are close to the side plates 2 at both ends, and the top of the side plate 2 is higher than the top edge of the wire rope 5 passing around the guide wheel 4, and the base plate 1 is provided with a connecting bolt 6 for fixing the base plate 1 to an external mechanism. When the device is used, the base plate 1 is first fixed to an external foundation by the connecting bolt 6, such as Figure 1 The steel beam 8 shown in the figure is then used to pass the steel wire rope 5 of the equipment around the guide wheel 4 and connect it to the hook, and finally the hook is used to lift the goods. The guide wheel 4 is an ordinary guide wheel with a groove, but the model needs to be selected according to the on-site usage to ensure that the steel wire rope 5 can be completely located in the groove of the guide wheel 4. The present application adopts a bracket structure composed of a base plate 1 and a side plate 2 to support the guide wheel 4. Since the two ends of the guide wheel 4 are close to the side plates 2 at both ends, and the side plates 2 are higher than the steel wire rope 5 wound on the guide wheel 4, it can well limit the steel wire rope 5 and avoid the situation where the steel wire rope 5 is out of the groove, thereby ensuring the stable operation of the lifting operation, reducing safety hazards and improving operation efficiency.

[0019] For some harsh lifting environments, such as strong winds on site, which easily cause the wire rope 5 to swing, or for some situations where oblique lifting is required, it is necessary to further improve the anti-drop performance of the wire rope. Figure 3 As shown, the pin shaft 3 includes two pin shafts 3, which are arranged side by side in the vertical direction on the side plate 2. The wheel surfaces of the guide wheels 4 on the two pin shafts 3 are close to each other, and the grooves on the wheel surfaces are aligned. The top of the side plate 2 is higher than the top edge of the wire rope 5 that bypasses the guide wheel 4 on the upper pin shaft 3. When in use, the wire rope 5 is passed through the groove between the two guide wheels 4, so that the wire rope 5 is confined in the cavity formed by the grooves of the two guide wheels 4. In this way, even if the wire rope 5 shakes or jumps greatly during the lifting process, the wire rope 5 will not be out of the groove. In addition, this structure also allows the wire rope to bypass the upper guide wheel 4, thereby realizing a variety of lifting combination usage methods and improving the applicability of the entire device.

[0020] In order to make the overall structure more perfect, the utility model also provides the following preferred solutions:

[0021] Generally, two strands of steel wire rope 5 are used in the process of lifting goods. Therefore, it is better to connect two guide wheels 4 on the pin shaft 3. The adjacent ends of the two guide wheels 4 are close to each other, and the other ends are close to the side plates 2 at both ends. The two guide wheels 4 rotate independently, and the steel wire ropes on the two guide wheels 4 can play the role of preventing them from falling out of the groove, while the two sides are restricted by the side plates 2.

[0022] In order to improve the stability of the entire support structure, such as Figure 2 As shown, a stiffening plate 7 is provided between the side of the side plate 2 away from the guide wheel 4 and the base plate 1. The stiffening plates 7 preferably include two, and are respectively provided between the two ends of the side plate 2 and the base plate 1.

[0023] In order to better fix the entire support structure on the external foundation, such as Figure 2As shown, the connecting bolts 6 should include at least four, two of which are arranged at intervals at both ends of the base plate 1, and the two connecting bolts 6 are located between the two stiffening plates 7, so as to ensure the reliability of the connection between the base plate 1 and the external foundation.

[0024] The utility model installs the guide wheel 4 by separately arranging a fixed bracket, so that the side plates 2 on both sides of the guide wheel 4 are close to the two sides of the guide wheel 4, and the top of the side plates 2 is higher than the top edge of the wire rope 5 bypassing the guide wheel 4. In this way, the side plates 2 can be used to limit the wire rope 5 on the guide wheel 4, avoiding the situation that the wire rope 5 falls out of the groove, thereby ensuring the stable operation of the lifting operation, reducing safety hazards and improving operation efficiency, and has good practicality and application value.
