Description

Technical Field

[0001] The utility model relates to the field of underground air doors, in particular to a mine air door synchronization device. Background Art

[0002] Underground ventilation is the top priority of underground safety production. In the existing technology, underground ventilation means generally include dampers and air ducts. The setting of the dampers has the function of supplying sufficient fresh air underground, diluting toxic gases underground, and regulating the underground air volume. Synchronous opening and closing of dampers can reduce the loss of wind power and improve the air exchange efficiency, but the synchronization of damper opening and closing is generally not high.

[0003] In order to solve the above problems, the applicant submitted application number 2022226235323, disclosing a mining pull-type synchronous damper, and application number 2021217030118, disclosing a mining screw-type synchronous damper. The above dampers can all control the synchronous opening and closing of the dampers, but their disadvantage is that the cost is relatively high, that is, the price of motor equipment is relatively high, and the maintenance cost is high once damaged. Based on the above, the applicant also proposed application number 2023224382089c, disclosing a mining dual-power damper control device, which uses a hydraulic cylinder or cylinder power mechanism to reduce the equipment cost and maintenance cost. However, its configuration structure is still unreasonable, that is, the transmission balance connecting rod of the equipment is the main force-bearing component, and the door opening requires the transmission balance connecting rod to be twisted. The transmission balance connecting rod is subjected to huge torque after long-term use, which is easy to cause deformation, and has a short service life, a short maintenance cycle, and complex maintenance. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a mining air door synchronization device with more reasonable structural configuration, low cost and maintenance cost, longer service life and longer maintenance cycle.

[0005] The device includes a push rod mechanism, which is the power unit of the device;

[0006] There are two push rod mechanisms in total, and the two push rod mechanisms are arranged opposite to each other;

[0007] A door panel push rod and a balancing connecting rod are hingedly arranged on the piston of the push rod mechanism;

[0008] One end of the door panel push rod is hinged on the piston of the push rod mechanism, and the other end is hinged on the door panel;

[0009] One end of the balancing connecting rod is hinged on the piston of the rod mechanism, and the other end is hinged on the synchronous connecting rod, that is, the balancing connecting rods hinged on the pistons of the two push rod mechanisms are respectively hinged on the two ends of the synchronous connecting rod;

[0010] The synchronous connecting rod is centrally provided with a rotary bearing.

[0011] Furthermore, the synchronous connecting rod is rotatably arranged on the door frame through a bearing.

[0012] The effect achieved in this way is that the piston action of the push rod mechanism directly acts on the door panel push rod to execute the door pushing action. The synchronous connecting rod no longer bears direct torque, but serves as a structural component for controlling the synchronization rate of the two dampers, thereby controlling the synchronous opening and closing of the dampers.

[0013] The beneficial effects of the utility model are as follows: the utility model solves the problem in the prior art that the wind door centralized control mechanism is easy to deform and has a short service life, and can ensure the safety of ventilation and wind control, high synchronization rate, low air leakage, and low construction and maintenance costs. At the same time, the structural configuration of the equipment is more reasonable, the service life is longer, and the maintenance frequency is lower. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Reference Figure 1 The utility model of a mine air door synchronization device includes a push rod mechanism 6, and the push rod mechanism 6 is the power unit of the device;

[0019] There are two push rod mechanisms 6 in total, and the two push rod mechanisms 6 are arranged opposite to each other;

[0020] The door panel push rod and the balance connecting rod 3 are hingedly arranged on the piston of the push rod mechanism 6;

[0021] One end of the door panel push rod is hinged on the piston of the push rod mechanism 6, and the other end is hinged on the door panel 1;

[0022] One end of the balancing link 3 is hinged on the piston of the rod mechanism, and the other end is hinged on the synchronous link 4, that is, the balancing link 3 hinged on the pistons of the two push rod mechanisms 6 are respectively hinged at both ends of the synchronous link 4;

[0023] The synchronous connecting rod 4 is centrally provided with a bearing 5 .

[0024] Furthermore, the synchronous connecting rod 4 is rotatably arranged on the door frame via a bearing 5 .

[0025] The effect achieved in this way is that the piston action of the push rod mechanism 6 directly acts on the door panel push rod to execute the door pushing action. The synchronous connecting rod 4 no longer bears direct torque, but serves as a structural component for controlling the synchronization rate of the two dampers, playing a role in controlling the synchronous opening and closing of the dampers.

[0026] Furthermore, the push rod mechanism 6 adopts a pneumatic cylinder or a hydraulic cylinder.

[0027] The effect achieved by this is that the synchronous damper configuration form based on the prior art has lower manufacturing and maintenance costs for the equipment.

[0028] In Example 1, the mining damper synchronization device is applied to a double-door-plate 1 split damper.

[0029] Example 2, refer to the accompanying drawings of the specification Figure 1 Two door panel push rods are hingedly arranged on the piston of each push rod mechanism 6, and the two door panel push rods are respectively hingedly arranged on the door panels 1 arranged oppositely.

[0030] That is, the device is applied to the opening and closing of the forward and reverse synchronous dampers for mining in the prior art.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.

Any figure mark in the claims should not be regarded as limiting the claims.
