Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide rails, in particular to an internal guide piece for guide rails with a positioning structure. Background Art

[0002] The reason why the elevator can run up and down smoothly is that in addition to the core operation system control, it also needs an auxiliary operation device, and the carrier of this equipment is the elevator guide rail. The existing elevator guide rails mainly include solid guide rails and hollow guide rails.

[0003] Since a single existing hollow guide rail is long and has a small cross-sectional area, it is difficult to ensure the connection accuracy of the ends when connecting two guide rails, making it difficult for the straightness of the track to meet the standards, increasing the difficulty of construction and affecting the stability and comfort of the elevator operation. Therefore, a connecting piece for a hollow elevator guide rail is needed to improve the above problems.

[0004] Chinese utility model patent CN202220720216.5 discloses a connecting piece for a hollow elevator guide rail, comprising a connecting piece body, a first elevator guide rail being installed on the left side of the connecting piece body, a second elevator guide rail being installed on the right side of the connecting piece body, and transfer holes being evenly provided at the middle of the front and rear side surfaces of the connecting piece body. By adapting the connecting piece body to the hollow cavities provided on the first and second elevator guide rails, the connection between the first and second elevator guide rails can be made convenient and smooth. By means of the transfer holes and the positioning holes, the connection between the connecting piece body and the first and second elevator guide rails can be made stable. By means of connecting holes being provided at the bottom of the connecting piece body corresponding to the mounting holes, the connection and positioning stability between the guide rails can be made stable.

[0005] However, it still has the following defects:

[0006] 1. The use of solid connecting parts increases the overall mass of the guide rail, and the solid connecting parts are prone to deformation, which affects the connection accuracy of the guide rail.

[0007] 2. It uses transfer holes and positioning holes to improve the docking stability between the two guide rails, but when the staff installs the guide rails for the first time, the positioning work is still difficult and inconvenient to use;

[0008] 3. When the elevator passes through the guide rail connection, the impact on the guide rail connection is transferred to the connecting guide. Since the connecting guide is solid, it is impossible to disperse and absorb the force. Summary of the invention

[0009] Technical problems to be solved by the utility model

[0010] The use of solid connecting parts increases the overall mass of the guide rails, and solid connecting parts are prone to deformation, which affects the connection accuracy of the guide rails. It uses adapter holes and positioning holes to improve the docking stability between the two guide rails, but when the staff first installs the guide rails, the positioning work is still difficult and inconvenient to use; when the elevator passes through the guide rail connection, the impact caused by the guide rail connection is transferred to the connecting parts. Since the connecting parts are solid, they cannot disperse and absorb the force.

[0038] Hereinafter, an inner guide for a guide rail having a positioning structure which is one embodiment of the present invention will be described with reference to the drawings.

[0039] Please refer to Figure 1-Figure 5 As shown, an internal guide member for a guide rail with a positioning structure comprises a guide member body 2, the guide member body 2 is used to connect two adjacent guide rail bodies 1, and a supporting mechanism is also arranged inside the guide member body 2;

[0040] Specifically, the support mechanism is used to protect the connection between the two connecting member bodies 2;

[0041] The guide rail body 1 is used to carry components such as the elevator car and brakes;

[0042] The guide rail body 1 is configured as a "U"-shaped stretching member, and a mounting hole 101 is opened on the outer wall of the guide rail body 1;

[0043] The connecting member body 2 is configured as a stretching member that fits the inner wall of the guide rail body 1;

[0045] Specifically, the spacing between the through holes 203 on the connecting member body 2 is the same as the spacing between the mounting holes 101 on the guide rail body 1;

[0046] More specifically, the positioning pad 201 is made of rubber material;

[0047] A positioning protrusion 202 is provided on the outer wall of each through hole 203 close to the mounting hole 101;

[0048] Specifically, the positioning protrusion 202 is configured as a circular ring, and the outer edge of the top end thereof is configured as an inclined surface;

[0049] More specifically, the positioning protrusion 202 can be embedded in the mounting hole 101;

[0050] During use, the two guide rail bodies 1 are placed on the outer wall of the connecting member body 2 and slid until the two guide rail bodies 1 are in contact with the positioning pads 201, and the positioning protrusions 202 on the connecting member body 2 are embedded in the mounting holes 101 on the guide rail body 1, and the guide rail body 1 and the connecting member body 2 are installed and fixed by mounting bolts;

[0051] Regarding the supporting institutions, including:
