Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of freight aerial ropeway, and particularly relates to a double-supporting cable gripper pressing plate device. BACKGROUND

[0002] In the freight aerial ropeway system using the four-bar linkage gravity type cable gripper, the connection between the freight car and the carrying cable is realized through the four-bar linkage gravity type cable gripper. In the production and operation process of the ropeway, the freight car and the carrying cable are not always connected together, that is, the freight car is connected with the carrying cable when running on the line, and is disconnected with the carrying cable when working in the station. The connection and disconnection between the four-bar linkage gravity type cable gripper and the carrying cable are realized at each station entrance, that is, when the freight car departs from the station, the four-bar linkage gravity type cable gripper is connected with the carrying cable at the station entrance, the freight car is pulled out of the station by the carrying cable, and runs on the ropeway line until it reaches the next station. When the freight car enters the next station, the four-bar linkage gravity type cable gripper is disconnected with the carrying cable at the entrance of the station, and the freight car enters the station for work.

[0003] In order to ensure that the four-bar linkage gravity type cable gripper can be reliably connected with the carrying cable when departing from the station, a cable gripper pressing plate device must be installed above the position where the four-bar linkage gravity type cable gripper is connected with the carrying cable, so that the center of the gripper jaw and the center of the carrying cable always remain concentric during the connection process. The existing cable gripper pressing plate device, as shown in Figs. 1 and 2, comprises a fixed frame, a limiting plate is arranged below the fixed frame, the fixed frame and the limiting plate are respectively connected and fixed with the steel structure in the station by means of bolts or welding, a pressing plate is arranged below the limiting plate, two groups of single-supporting elastic pressing mechanisms are arranged in parallel on the left and right of the fixed frame, each group of single-supporting elastic pressing mechanisms comprises a pressing rod, a limiting piece, a sliding bearing and a compression spring, the sliding bearing is installed on the fixed frame, the pressing rod is vertically passed through the shaft hole of the sliding bearing and the limiting plate in sequence and is welded with the pressing plate, the limiting piece is arranged above the sliding bearing and is connected with the pressing rod; the compression spring is sleeved on the pressing rod and is pressed tightly by the limiting plate and the pressing plate, the upper part of the cable gripper is pressed by the elastic force of the spring, so that the cable gripper is connected with the carrying cable. However, it is found that the reliability of the connection between the cable gripper and the carrying cable after being pressed is very poor, the cable gripper cannot reliably hold the carrying cable, thereby causing the freight car to fall off the line, causing the occurrence of car falling and line jumping accidents, and affecting the safe and stable operation of the ropeway. Figure 3 and Figure 4 SUMMARY

[0004] The purpose of the present application is to solve the above technical problems, and to provide a double-supporting cable gripper pressing plate device capable of reliably connecting the cable gripper with the carrying cable.

[0005] In order to achieve the above purpose, the technical scheme of the present application is as follows:

[0006] ​The double-support rope holder pressing plate device comprises a pressing plate and a fixed frame, at least two groups of double-support elastic mechanisms are arranged in parallel on the fixed frame, the pressing plate is arranged transversely below the double-support elastic mechanisms, and the lower end of each group of double-support elastic mechanisms is movably connected to the pressing plate through a corresponding hinged assembly.

[0007] Each group of double-support elastic mechanisms comprises:

[0008] Two sliding bearings are arranged on the fixed frame in a spaced-apart manner, and the shaft holes of the upper and lower sliding bearings are opposite to each other.

[0009] A pressing rod is arranged in the shaft holes of the upper and lower sliding bearings, and the pressing rod moves along the axis of the sliding bearings.

[0010] A first limiting member is arranged above the upper sliding bearing and connected to the pressing rod.

[0011] A second limiting member is arranged above the lower sliding bearing and connected to the pressing rod.

[0012] A compression spring is sleeved on the pressing rod and is compressed at the lower end of the upper sliding bearing and the upper end of the second limiting member by the first limiting member and the second limiting member.

[0013] As a further technical solution, each hinged assembly comprises a U-shaped seat and a connecting shaft, the U-shaped seat is fixed on the pressing plate, the lower end of the pressing rod is inserted into the U-shaped seat after passing through the shaft hole of the lower sliding bearing, and the lower end of the pressing rod and the U-shaped seat are movably connected by the connecting shaft.

[0014] As a further technical solution, the axis of the connecting shaft is perpendicular to the plane formed by the axis of the pressing rod and the center line of the length direction of the pressing plate.

[0015] As a further technical solution, the fixed frame comprises an upper cross beam and a lower cross beam arranged in parallel, a space is arranged between the upper cross beam and the lower cross beam, the upper sliding bearing is fixedly arranged on the upper cross beam, and the lower sliding bearing is fixedly arranged on the lower cross beam.

[0016] As a further technical solution, the first limiting member and the second limiting member are nuts, and the nuts are threadedly connected to the pressing rod.

[0017] Compared with existing technologies, the advantages of this invention are as follows: This invention connects the pressure plate to the lower end of the pressure rod via a connecting shaft. The pressure rod, supported by both upper and lower sliding bearings, forms a double-support structure, greatly improving the flexibility and stability of the pressure plate's vertical movement. This ensures that the pressure plate reliably presses against the upper part of the gripper's head during the connection process of the four-bar gravity-type cable gripper, restraining the upward movement of the gripper head and ensuring that the center of the gripper's jaws remains concentric with the center of the transport cable. This guarantees a reliable connection between the gripper and the transport cable, ensuring the quality of the connection and effectively eliminating the potential hazard of the freight car falling off the cableway line. It also prevents accidents such as derailment and cable jumps, ensuring the safe and stable operation of the cableway. Furthermore, this invention has a simple structure and a long service life.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited to the scope shown in the embodiments. Example 1:

[0024] like Figure 1 As shown, a double-supported cable gripper pressure plate device includes a pressure plate 1, which is a commonly used pressure plate 1 structure in the art, used to press down the upper part of the gripper head.

[0025] The fixed frame 2 is a rectangular frame structure in this embodiment, which is made of profile steel and is fixed to the steel structure in the station by bolts or welding. The rectangular frame includes upper cross beams 201 and lower cross beams 202 arranged in parallel, and a space is provided between the upper cross beams 201 and the lower cross beams 202, and the space is set according to the stroke of the compression spring. Of course, the structure of the fixed frame 2 is not limited to the rectangular frame structure, and other shapes can also be designed to include the technical feature of the parallel arrangement of the upper cross beams 201 and the lower cross beams 202 and the space provided between the upper cross beams 201 and the lower cross beams 202.

[0026] Two groups of double-support elastic mechanisms 3 are arranged in parallel on the fixed frame 2; the pressing plate 1 is arranged transversely below the double-support elastic mechanisms 3, and the lower end of each group of double-support elastic mechanisms 3 is movably connected to the pressing plate 1 through a corresponding hinge assembly 4; each group of double-support elastic mechanisms 3 includes:

[0027] A sliding bearing, which is a commonly used part in the art, is provided with two upper sliding bearings 301 fixedly installed on the upper cross beams 201 and two lower sliding bearings 302 fixedly installed on the lower cross beams 202, and the shaft holes of the upper sliding bearings 301 and the lower sliding bearings 302 are opposite to each other;

[0028] A pressurizing rod 303, the upper and lower ends of which are respectively installed in the shaft holes of the upper sliding bearings 301 and the lower sliding bearings 302, so that the pressurizing rod 303 moves along the axis direction of the sliding bearings;

[0029] A first limiting piece 304, which is a nut, is arranged above the upper sliding bearings 301 and is threadedly connected with the pressurizing rod 303 and moves simultaneously with the pressurizing rod 303; when the pressurizing rod 303 is pressed down, the first limiting piece 304 abuts against the upper sliding bearings 301 to prevent the pressurizing rod 303 from coming out of the upper sliding bearings 301; and a second limiting piece 305, which is a nut, is arranged above the lower sliding bearings 302 and is threadedly connected with the pressurizing rod 303;

[0030] A compression spring, which is sleeved on the pressurizing rod 303, is compressed at the lower end of the upper sliding bearings 301 and the upper end of the second limiting piece 305 by the first limiting piece 304 and the second limiting piece 305. When the cable gripper passes through the pressing plate device by the carrier cable, the elasticity of the compression spring provides the force of mutual pressing of the upper part of the cable gripper head and the pressing plate 1.

[0031] As Figure 2As shown in the drawings, each set of the articulated assembly 4 comprises a U-shaped seat 401 fixed on the pressing plate 1 and a connecting shaft 402, the lower end of the pressing rod 303 is inserted into the U-shaped seat 401 after passing through the shaft hole of the lower sliding bearing 302, and the lower end of the pressing rod 303 and the U-shaped seat 401 are movably connected by the connecting shaft 402. The shaft center of the connecting shaft 402 is perpendicular to the plane formed by the shaft center line of the pressing rod 303 and the center line of the length direction of the pressing plate 1, so that the pressing plate 1 can realize multi-directional change along the position passed by the cable gripper.

[0032] The working process of the present application is that when the cable gripper comes to the lower side of the pressing plate 1 along the carrying cable, the head of the cable gripper lifts the pressing plate 1, at this time, the elastic action of the compression spring generates a counter thrust on the pressing plate 1, and the pressing plate 1 is movably connected with the lower end of the pressing rod 303 through the connecting shaft 402 and is supported by the double support point structure, so that the head of the cable gripper and the pressing plate 1 are always tightly pressed.

[0033] The present application finds that the reason why the reliability of the connection between the cable gripper and the carrying cable is very poor is that the center of the jaw of the cable gripper cannot always be consistent with the center of the carrying cable. Figure 3 and Figure 4 As shown in the drawings, during the pressing process, the pressing plate 1 has poor flexibility in moving up and down, and when the cable gripper passes through the pressing plate 1, the pressing rod and the sliding bearing are easily stuck and stopped for a short time. Therefore, the present application movably connects the pressing plate 1 with the lower end of the pressing rod 303 through the connecting shaft 402, and cooperates with the pressing rod 303 supported by the upper sliding bearing 301 and the lower sliding bearing 302 to form a double support point structure, which greatly improves the flexibility and stability of the pressing plate 1 in moving up and down, so that the pressing plate 1 can always reliably and tightly press the upper part of the head of the cable gripper during the connection process of the four-link gravity cable gripper, and the lifting of the head of the cable gripper is constrained, so that the center of the jaw of the cable gripper and the center of the carrying cable are always concentric, thereby reliably connecting the cable gripper with the carrying cable, ensuring the quality of the connection of the cable gripper, effectively eliminating the hidden danger of the falling of the truck on the cableway line, avoiding the occurrence of the accidents of the falling of the truck and the jumping of the cable, and ensuring the safe and stable operation of the cableway.
