Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction elevator cable protection technology, specifically to a construction elevator cable protection device. Background Technology
[0002] Construction elevators, also known as construction hoists, consist of several parts, including a car, drive mechanism, standard sections, wall attachments, chassis, railings, and electrical system. They are commonly used construction machinery for carrying people and goods. Due to their unique box-like structure, they are both comfortable and safe to ride. Construction elevators are usually used in conjunction with tower cranes on construction sites. Their load capacity is generally between 0.3 and 3.6 tons, and their operating speed varies from 1 to 96 m / min.
[0003] The protection of construction elevator cables is a crucial aspect of ensuring the safe operation of construction elevators. Typically, the protection of construction elevator cables uses two rubber blocks as valves. Under repeated alternating stress, these rubber blocks are prone to breakage and failure. As a result, during the elevator's descent, the cable can easily come off the protective device, causing cable damage and potentially leading to electric shock accidents. This affects the reliability and safety of the construction elevator's operation, and the cable disassembly is not convenient. Therefore, a construction elevator cable protection device is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a cable protection device for construction elevators to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a construction elevator cable protection device, comprising: a protective frame,
[0006] The positioning component, located on the inner wall of the protective frame, is used to limit the cable and prevent it from coming out of the protective frame;
[0007] A locking component, located on the outer wall of the protective frame, is used to lock the positioning plate, keeping it in the open position;
[0008] The locking assembly includes a locking plate that is adapted to a rotating plate. A fixing rod is provided on the inner wall of one end of the locking plate, a fixing ring is provided on the outer wall of the bottom of the fixing rod, and a push plate is provided on the outer wall of the fixing ring. The push plate is located at the bottom of the inner wall of the hollow column.
[0009] Preferably, the fixing rod is located on the inner wall of the hollow column, and a spring is provided on the outer wall of the fixing rod. The spring is located inside the hollow column and above the push plate.
[0010] Preferably, the inner wall of the protective frame is provided with a rubber pad, and a connecting rod is provided on one side of its outer wall.
[0011] Preferably, the positioning component includes a fixing seat, which is located on both sides of the inner wall of the protective frame. The fixing seats are connected to each other by a fixing shaft, and a baffle is provided on one side of the fixing seat.
[0012] Preferably, torsion springs are symmetrically arranged on the outer wall of the fixed shaft, and the torsion springs are located between the positioning plate and the fixed seat.
[0013] Preferably, a rotating plate is provided on the top outer wall of the fixed shaft, and the rotating plate is adapted to one end of the locking plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This construction elevator cable protection device, through the combined action of the locking plate and the rotating plate, can limit and fix the positioning plate, thereby preventing the cable from detaching from the protective frame, effectively ensuring the safety of the construction elevator cable, and improving the reliability and safety of the construction elevator operation. When it is necessary to remove the cable, removing the locking component's limitation on the rotating plate can simultaneously remove the limitation operation of the torsion springs at both ends of the positioning plate. Pushing the cable outward will cause the cable to drive the positioning plate to rotate until the cable detaches from the outside of the protective frame. After the cable detaches, the positioning plate returns to its original position under the action of the torsion spring, thereby improving the practicality of the device and making the disassembly and replacement of the cable more convenient.

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.

Therefore, they should not be construed as limitations on this utility model.
[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a construction elevator cable protection device, including a protective frame 1. The protective frame 1 is made of high-strength engineering plastics (such as PEEK, CFRP, etc.) or lightweight alloy materials (such as aluminum alloy, magnesium alloy, etc.), which have good impact resistance and corrosion resistance. Its shape is square, which is convenient for installation on the construction elevator. One end of the protective frame 1 has an opening to facilitate the entry and exit of the cable, and it is used to fix and support other components, providing an overall protective space for the cable. The positioning component 2 is set on the inner wall of the protective frame 1 to limit the cable and prevent it from coming out of the protective frame 1. The locking component 3 is set on the outer wall of the protective frame 1 to lock the positioning plate 202 and keep it in the open state.
[0025] like Figure 1-4As shown in the embodiment of this application, a rubber pad 102 is provided on the inner wall of the protective frame 1, and a connecting rod 101 is provided on one side of its outer wall. Specifically, when performing cable protection work, the connecting rod 101 is used to fix the protective frame 1 at the corresponding position of the construction elevator. The rubber pad 102 is fixedly provided on the inner wall of the protective frame 1. The rubber pad 102 can buffer and protect the cable when it shakes inside the protective frame 1, preventing the cable from directly contacting the inner wall of the protective frame 1. One end of the rubber pad 102 is in contact with the baffle 204, and the thickness of the rubber pad 102 is equal to the length of the baffle 204. It should be noted that the rubber pad 102 can buffer the alternating stress generated by the movement of the cable, reduce its impact on the protective frame 1, and protect the inner wall of the protective frame 1 from damage.
[0026] like Figure 1-4 As shown in the embodiments of this application, the locking component 3 includes a locking plate 301, which is adapted to the rotating plate 206. A fixing rod 304 is provided on the inner wall of one end of the locking plate 301, and a fixing ring 305 is provided on the outer wall of the bottom of the fixing rod 304. A push plate 306 is provided on the outer wall of the fixing ring 305. The push plate 306 is located at the bottom of the inner wall of the hollow column 302. Specifically, the locking plate 301 is used to limit the rotating plate 206. The locking plate 301 is provided with a groove adapted to the rotating plate 206. The rotating plate 206 is a limiting square, thereby limiting the rotation of the rotating plate 206. When the positioning plate 202 drives the rotating plate 206 to rotate, the rotating plate 206 can be in the same state after rotation as before it is not rotated, thereby ensuring that the locking plate 301 can continuously limit and fix the rotating plate 206. A fixing rod 304 is fixedly provided on the inner wall of one end of the locking plate 301. With the fixing ring 305, the fixing rod 304 is rotatably connected to the push plate 306. The push plate 306 is adapted to the inner wall of the hollow column 302. The inner wall of the hollow column 302 is square, which can ensure that the push plate 306 is not affected when the fixing rod 304 rotates.
[0027] like Figure 1-4As shown in the embodiment of this application, the fixing rod 304 is located on the inner wall of the hollow column 302, and a spring 303 is provided on the outer wall of the fixing rod 304. The spring 303 is located inside the hollow column 302 and above the push plate 306. Specifically, when performing cable protection work, a handle is provided at the top of the locking plate 301. The locking plate 301 is lifted by the handle, so that the locking plate 301 is disengaged from the rotating plate 206. During the upward movement of the locking plate 301, the push plate 306 below the fixing rod 304 on one end of its inner wall drives the spring 303 to be compressed. Then, the locking plate 301 drives the fixing rod 304 to rotate. When the fixing rod 304 rotates, it will bring... When the locking plate 301 is rotated and the force on the locking plate 301 is removed, the locking plate 301 moves downward under the elastic potential energy of the spring 303. At this point, the locking plate 301 is no longer in contact with the rotating plate 206. The handle on the positioning plate 202 is used to rotate the positioning plate 202. During the rotation of the positioning plate 202, the torsion spring 203 and the rotating plate 206 will rotate synchronously. After rotating 90°, the above operation is repeated in the opposite direction, so that the locking plate 301 can cooperate with the rotating plate 206 again to lock the rotating plate 206, thereby limiting the current state of the positioning plate 202 so as to facilitate the placement of the cable into the protective frame 1.
[0028] like Figure 1-4 As shown in the embodiment of this application, the positioning component 2 includes a fixing seat 201, which is located on both sides of the inner wall of the protective frame 1. The fixing seats 201 are connected to each other by a fixing shaft 205, and a baffle 204 is provided on one side. Specifically, the fixing seats 201 are located on both sides of the inner wall of the protective frame 1 and are fixedly connected to the protective frame 1. The fixing seats 201 do not contact the rubber pad 102, and there is a distance of the width of the baffle 204. The fixing shaft 205 is rotatably connected to the fixing seat 201. The baffle 204 is used to limit the positioning plate 202, thereby hindering the rotation of the positioning plate 202. Under the action of the baffle 204 and the protective frame 1, the positioning plate 202 can only rotate 90° toward the outer wall of the protective frame 1. After the positioning plate 202 is opened, the cable can be placed into the protective frame 1.
[0029] like Figure 1-4As shown in the embodiment of this application, torsion springs 203 are symmetrically arranged on the outer wall of the fixed shaft 205. The torsion springs 203 are located between the positioning plate 202 and the fixed seat 201. A rotating plate 206 is arranged on the top outer wall of the fixed shaft 205. The rotating plate 206 is adapted to one end of the locking plate 301. Specifically, the torsion springs 203 on the outer wall of the fixed shaft 205 are used to control the rotation of the positioning plate 202, and the rotating plate 206 is also used to drive the positioning plate 202 to rotate. Under the cooperation of the rotating plate 206 and the locking plate 301, the rotation of the positioning plate 202 can be restricted, and the state of the positioning plate 202 after rotation can be maintained. When protecting the cable, the cable needs to be placed in the protective frame 1, and the locking component 3 should be removed in advance. To limit the rotation plate 206, a handle is provided on the positioning plate 202. The construction worker uses the handle to rotate the positioning plate 202. When the positioning plate 202 rotates 90°, the opening end of the protective frame 1 is in an open state. At this time, the rotation plate 206 also rotates 90°. The locking component 3 limits the rotation plate 206, so that the positioning plate 202 is always in a vertical state, which keeps the opening end of the protective frame 1 in a continuously exposed state. At this time, the torsion spring 203 is also controlled by the locking component 3. It should be noted that when the positioning plate 202 is in a horizontal state, the positioning plates 202 on both sides of the inner wall of the protective frame 1 are connected together, which can close the opening end of the protective frame 1.
[0030] The working principle of this utility model is as follows:
[0031] Using connecting rod 101, the protective frame 1 is fixed in a suitable position on the construction elevator. When protecting the cable, the cable needs to be placed within the area formed between the protective frame 1 and the positioning plate 202. Initially, the locking component 3 and the positioning component 2 are not in contact. The construction worker pulls the handle, rotating the positioning plate 202 90°. During this rotation, the torsion spring 203 and the rotating plate 206 rotate synchronously. At this time, the torsion spring 203 generates elastic potential energy. Because the torsion spring 203 can return to its original position after the positioning plate 202 rotates... In its original position, the positioning plate 202 needs to be rotated 90° for cable installation. To achieve this, the locking plate 301 is lifted, and the fixing rod 304 is used to rotate it. As the locking plate 301 is lifted, the spring 303 is compressed. Once the locking plate 301 is directly above the rotating plate 206, the force on the locking plate 301 is released. Under the action of the spring 303, the locking plate 301 enters the outer wall of the rotating plate 206 and locks it, thus keeping the positioning plate 202 in a 90° rotation state and restricting the torsion spring 202. After the cable installation is completed, the locking plate 301 is removed from the limiting position of the rotating plate 206, and the locking plate 301 is turned to the back of the protective frame 1. The force applied to the locking plate 301 is removed, and the locking plate 301 moves downward under the action of the spring 303. At this time, the locking plate 301 is no longer limited by the rotating plate 206, and the elastic potential energy of the torsion spring 203 can be released, thereby restoring the positioning plate 202 to its original position. Under the action of the baffle 204, the positioning plate 202 will not rotate excessively, thus allowing the cable to proceed smoothly. The cable is positioned within the protective frame 1 by a limit switch. When the positioning plate 202 returns to its original position, the locking plate 301 again limits the handle, ensuring that the cable will not detach from the protective frame 1. When the cable needs to be removed, simply remove the locking component 3 from the limit switch on the rotating plate 206, and then push the cable outward from the protective frame 1. The cable will cause the positioning plate 202 to rotate, thus removing the cable. After the cable is removed, the positioning plate 202 will automatically return to its original position under the action of the torsion spring 203.
[0032] In summary, this utility model discloses a construction elevator cable protection device, including a protective frame 1, a positioning component 2, which is disposed on the inner wall of the protective frame 1 to limit the cable and prevent it from coming out of the protective frame 1, and a locking component 3, which is disposed on the outer wall of the protective frame 1 to lock the positioning plate 202 and keep it in the open state. With the cooperation of the locking plate 301 and the rotating plate 206, this utility model can limit and fix the positioning plate 202, thereby preventing the cable from coming out of the protective frame 1, effectively ensuring the safety of the construction elevator cable, and improving the reliability and safety of the construction elevator operation. When it is necessary to remove the cable, the locking component 3 can be removed from limiting the rotating plate 206, and the torsion springs 203 at both ends of the positioning plate 202 can be removed simultaneously. Pushing the cable outward, the cable will drive the positioning plate 202 to rotate until the cable comes out to the outside of the protective frame 1. After the cable comes out, the positioning plate 202 returns to its original position under the action of the torsion springs 203, thereby improving the practicality of the device and making the disassembly and replacement of the cable more convenient.
