Abstract
The utility model relates to a connecting and fixing structure for a connector of a hydraulic support. The connecting and fixing structure comprises the connector, a pin shaft, two semi-rings, a pressure plate and a cotter pin, wherein one end of the connector is connected with the push rod of a hydraulic support; the other end of the connector is connected with a scraper conveyor; the pin shaft is arranged at the connecting parts of the connector and the scraper conveyor, and is arranged in the pin shaft holes of the connector and the scraper conveyor; the shaft diameter at one end of the pin shaft is larger than the diameter of the pin shaft hole of the connector; a groove structure and a pin hole are formed at the other end of the pin shaft; the semi-rings are arranged at the groove part of the pin shaft; and the pressure plate is arranged outside the semi-rings and are in surface contact with the connector, so as to position the pressure plate. The connecting and fixing structure has the advantages that reliability in connection is guaranteed; the structure is simplified; the processing and the disassembly are more convenient; and the practicability is realized.
Description
Technical field
The utility model relates to the connection fixed structure of hydraulic support connecting portion.
Background technology
Use hydraulic support in the coal mine machinery in a large number; The type of attachment of hydraulic support and drag conveyor is to accomplish through effective fit system of parts such as connector, bearing pin, and union piece is to guarantee to prop up hydraulic support to pass and move frame action vital part correct, that reliably accomplish.Connected mode is through realizing (type of attachment is seen Fig. 1) in the endoporus that bearing pin 2 is inserted hydraulic support connector 1 and drag conveyor link 3.According to the real work situation, require this syndeton when guaranteeing reliability, require to reach as far as possible simple in structure, easy to operate, dismantle fast, therefore, to the certain requirement of fastening means proposition of bearing pin and connector.
The fastening form of existing bearing pin mainly contains following two kinds of structures:
A kind of is to cooperate with nut 6 through the screw thread on bearing pin 27 to form screw connection structure, with bearing pin 2 and connector 1 fixing (fastening form is seen Fig. 2).Owing in moving frame and pushing and sliding process, receive power and moment of flexure effect, cause the form of thread structural change, produce certain difficulty when causing this kind mode to be dismantled; Simultaneously, the dismounting difficulty also can be caused owing to the underground water of down-hole fully-mechanized mining working, mine and the long term that moves the depositing dust spraying in the frame process possibly produce the screw thread corrosion in the threaded connection place, reduces operating efficiency; In addition because in the coal mining process, drop coal cinder, spoil, the time regular meeting smash the screw thread on the bearing pin, cause the dismounting maintenance difficult.
Another kind is the fixedly (see figure 3) that realizes bearing pin 2 and connector 1 through cottor pin 8, packing ring 7.This frame mode is prone to cause the connector distortion when bearing larger axis to power, even fracture, influences connection reliability and stability.
Summary of the invention
The purpose of the utility model is reliable, simple in structure, the handling ease of a kind of connection of design, and the hydraulic support of convenient disassembly connects fixed structure.
The hydraulic support connector that the utility model proposes connects fixed structure, and it comprises connector and bearing pin, and bearing pin inserts in the axis hole of connector and transporter ledge, realizes that through the diameter of axle step of bearing pin one end connector contacts axial location with pin roll end face.It is characterized in that: also include two semi-rings and platen and cottor pin; There is a circle groove insertion of said bearing pin and the termination that is exposed to an end of connector, and on groove, have a pin-and-hole radially; Said two semi-rings are arranged in the bearing pin groove, and fit form is a matched in clearance, and the diameter of semi-ring is greater than the diameter of axis hole, and the end face of semi-ring contacts with the groove end face realizes axial location; Said platen is enclosed within outside bearing pin termination and the semi-ring, realizes that with semi-ring the hole axle cooperates, and contacts with connector formation face, thereby realize the platen location, on platen, has pin-and-hole, and is corresponding with pin-and-hole on the bearing pin, inserts cottor pin.
The utility model innovation part is:
1. use semi-ring, platen, bearing pin, cottor pin cooperation assurance, can prevent the distortion in the connector course of work, have location accuracy and fastening reliability;
2. connection and fastening structure help axial force and the moment of flexure that effective distributed elements is born, and guarantee connection safety, reliability.
3. simple in structure, parts are easy to process, avoid the dismounting difficulty or the workpiece work problem on deformation that are prone in traditional syndeton, raise labour efficiency.

The specific embodiment
Specify below in conjunction with the specific embodiment of accompanying drawing the utility model.
Referring to Fig. 4, this hydraulic support connector connects fixed structure and includes connector 1, bearing pin 2, semi-ring 3, platen 4 and cottor pin 8.Connector 1 two ends connect hydraulic support push rod and scratch board conveyor ledge respectively.
The structure of bearing pin 2 is as shown in Figure 5, and the bearing pin one end diameter of axle is greater than connector bearing pin aperture, and the other end is an insertion end, and it inserts in connector and the transporter link axis hole, realizes that through the bearing pin diameter of axle step connector contacts axial location with pin roll end face.There is a circle groove insertion of bearing pin 2 and the termination that is exposed to an end of connector, and on groove, have a pin-and-hole radially.
The structure of platen 4 is as shown in Figure 7, and it is enclosed within outside bearing pin 2 terminations and the semi-ring 3, realizes that with semi-ring the hole axle cooperates, and contacts with connector formation face, thereby realize the platen location.On platen 4, have pin-and-hole, corresponding with pin-and-hole on the bearing pin 2, insert cottor pin 8.
Cooperated with the effective of cottor pin 8 by above platen 4, semi-ring 2, it is fixing just can to realize that connector 1 is connected with bearing pin 2.
Protection scope of the present invention is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and do not depart from the scope of the present invention and spirit the present invention.If these changes and distortion belong in the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and is out of shape interior.
