Description

Technical Field

[0001] This utility model relates to the technical field of cage receiving devices, and in particular to a flat rocking table. Background Technology

[0002] In mines using cage hoisting, because mine cars and personnel need to enter and exit at each level, a cage support device is necessary to connect the tracks or platforms inside the cage with the fixed tracks or platforms at each level for normal hoisting. A folding platform is a type of cage support device that can be used at the mine entrance, bottom, and intermediate levels. Currently, the folding platform has become the main support device for cages in auxiliary shaft hoisting, connecting the mine entrance and bottom car yards to the tracks inside the cage to complete loading and unloading operations. With the development of mining technology, the load-bearing requirements of the folding platform have increased, and it must also accommodate the operation of various vehicles. The folding platform needs to support both rail-mounted mine cars and trackless vehicles, requiring reinforcement. However, if the drive mechanism loses power while the folding platform is raised, the platform may suddenly rotate due to gravity, posing a safety hazard. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a flat rocking table that uses a linkage structure and a limiting plate to form a self-locking mechanism to ensure the safety of the rocking table in the raised state.

[0004] To achieve the above objectives, this utility model provides a flat rocking table, comprising a first mounting beam and a second mounting beam arranged in the same direction, including:

[0005] The receiving platform has one end hinged to the upper end of the first mounting support beam;

[0006] The swing arm support has one end of its upper surface connected to the lower end of the first mounting beam, and the other end of its upper surface is provided with a curved swing arm. The curved swing arm has a bending protrusion facing away from the swing arm support, and the center of the curved swing arm is hinged to the swing arm support to form a first hinge point.

[0007] The upper end of the connecting rod is hinged to the lower surface of the receiving platform to form a second hinge point, and the lower end of the connecting rod is hinged to the upper end of the curved swing rod to form a third hinge point, so that the connecting rod and the curved swing rod form a linkage mechanism.

[0008] A drive cylinder having a telescopic end and a fixed end, the fixed end being hinged to the second mounting support beam;

[0009] The curved rocker arm is configured to rotate around the rocker arm support with the first hinge point as the rotation center under the drive of the drive cylinder. The side wall of the rocker arm support is provided with a limit plate. The position of the limit plate is configured such that after the second hinge point passes through the line connecting the first hinge point and the third hinge point, it limits the clockwise rotation of the curved rocker arm, so that when the drive cylinder loses power, the receiving platform is in a raised and locked state.

[0010] Furthermore, a receiving platform support is provided at the upper end of the first mounting beam, and a receiving platform rotation shaft is provided on the receiving platform support. The receiving platform and the receiving platform support are connected through the receiving platform rotation shaft to form a hinge connection with the first mounting beam.

[0011] Furthermore, a drive cylinder support is provided at the lower end of the second mounting beam, and the fixed end of the drive cylinder is hinged to the second mounting beam through the drive cylinder support.

[0012] Furthermore, a steel rail is fixedly connected to the receiving platform, and a rail tip is hinged to the steel rail. The rail tip is used to bridge the rail on the cage and the steel rail, so that the rail vehicle can pass on the receiving platform.

[0013] Furthermore, the rail is provided with a rocker tip shaft, and the rail rocker tip is hinged to the rail via the rocker tip shaft.

[0014] Furthermore, the drive cylinder is equipped with a hydraulic balance valve with a safety valve to balance the gravity load of the receiving platform and reduce the impact on the cage during the connection.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0016] (1) This utility model uses a linkage structure and a limiting plate to form a mechanical self-locking mechanism, which ensures that the rocking platform can remain locked even if the drive cylinder loses power when it is in the raised state, thereby significantly improving safety and avoiding the risk of the rocking platform falling unexpectedly when the traditional hydraulic system fails or the oil cylinder fails.

[0017] (2) The receiving platform of this utility model adopts a double-bearing arm plate structure, which enables the rocking platform to withstand greater loads and is suitable for different types of vehicle transportation, including rail-mounted mining cars and trackless vehicles. In particular, its wedge-shaped end design and bottom arc treatment enhance the effective overlap with the cage track and compensate for the positional deviation of the cage height.

[0018] (3) The entire working process of the receiving platform of this utility model is controlled by the drive cylinder, realizing the controllability of the working speed. In addition, the hydraulic balance valve equipped on the drive cylinder can ensure that the rocking platform has a certain floating when the load changes greatly, reducing the impact on the cage, while ensuring stable operation.

[0032] The receiving platform 1 has one end hinged to the upper end of the first mounting support beam 2;

[0033] The swing arm support 3 has one end of its upper surface connected to the lower end of the first mounting beam 2, and the other end of its upper surface is provided with a curved swing arm 7. The curved protrusion of the curved swing arm 7 faces away from the swing arm support 3, and the center of the curved swing arm 7 is hinged to the swing arm support 3, forming a first hinge point; as one embodiment, such as Figure 5 As shown, the center of the curved rocker arm 7 is provided with a rocker arm bearing 6, and the two ends of the rocker arm bearing 6 are connected to the rocker arm support 3 to realize the hinge connection between the center of the curved rocker arm 7 and the rocker arm support 3.

[0034] Link 11, the upper end of which is hinged to the lower surface of receiving platform 1, forming a second hinge point, and the lower end of link 11 is hinged to the upper end of curved swing rod 7, forming a third hinge point, so that link 11 and curved swing rod 7 form a linkage mechanism; Figure 1 As shown in the figure, in one embodiment, a swing arm support 12 is provided on the lower surface of the receiving platform 1, and the connecting rod 11 is rotatably connected to the swing arm support 12;

[0035] The drive cylinder 8 has a telescopic end and a fixed end, with the fixed end hinged to the second mounting support beam 10.

[0036] The curved rocker arm 7 is configured to rotate around the rocker arm support 3 with the first hinge point as the rotation center under the drive of the drive cylinder 8. A limit plate 17 is provided on the side wall of the rocker arm support 3. The limit plate 17 is used to limit the clockwise rotation of the curved rocker arm 7 after the second hinge point passes through the line connecting the first and third hinge points, so that when the drive cylinder 8 loses power, the receiving platform 1 is in a raised and locked state. The clockwise direction is based on... Figure 1 The indicated direction.

[0037] Furthermore, a receiving platform support 13 is provided at the upper end of the first mounting beam 2, and a receiving platform rotation shaft 14 is provided on the receiving platform support 13. The receiving platform 1 and the receiving platform support 13 are connected through the receiving platform rotation shaft 14 to form a hinged connection with the first mounting beam 2.

[0038] Optionally, the bottom of the receiving platform 1 and the overlapping part with the rail lining are made into an arc to ensure effective overlap with the cage within a certain angle range and to compensate for the height position deviation of the cage.

Simultaneously, it ensures that the flat platform can float with the cage under large load changes. When loading and unloading are complete, a signal is given to raise the flat platform. At this time, the piston rod of the drive cylinder 8 extends outward, and the swing arm rotates, driving the connecting rod 11 to raise the receiving platform 1. The drive cylinder 8 stops once the platform is in position. The entire working process of the receiving platform 1 is controlled by the drive cylinder 8, achieving controllable working speed.
