Description

TECHNICAL FIELD

[0001] The utility model belongs to elevator guide rail technical field, concretely relates to a fixing structure of elevator guide rail. BACKGROUND

[0002] The elevator guide rail provides precise vertical guidance for the elevator car and the counterweight device, ensuring that they run up and down along the predetermined trajectory in the shaft, preventing the car and the counterweight from swinging or deviating laterally during operation.

[0003] The conventional installation method of the elevator guide rail is to use a steel structure as support, and a measuring device is used to level the guide rail during installation to ensure the stability of the elevator during operation.

[0004] Because the elevator will vibrate during operation, it is usually necessary to apply lubricating oil or clean the guide rail during maintenance. If the verticality of the guide rail deviates, the steel structure at the damaged position needs to be removed and reinstalled before leveling the guide rail. This method not only causes frequent disassembly and maintenance of the steel fixing structure, resulting in high elevator maintenance cost, but also affects the stability of the fixed guide rail. On the other hand, it is not convenient to quickly level the guide rail, and the operation is not convenient and complex. UTILITY MODEL CONTENTS

[0024] In order to make the purpose and advantages of the utility model more clear and apparent, the utility model is specifically described below in combination with examples. It should be understood that the following text is merely used to describe one or several specific embodiments of the utility model and does not strictly limit the scope of protection specifically requested by the utility model.

[0025] As shown in Figures 1-5 A fixing structure of an elevator guide rail, comprising a guide rail main body 1, the guide rail main body 1 is a T-shaped structure, the left and right side edges of the guide rail main body 1 are respectively clamped with clamping plates 2, the clamping plates 2 are U-shaped, and connecting pieces are arranged between the clamping plates 2 and the guide rail main body 1.

[0026] The rear side walls of the clamping plates 2 are fixedly connected with supporting beams 3, the rear side walls of the supporting beams 3 are fixedly connected with mounting plates 4, a plurality of mounting holes are formed in the side walls of the mounting plates 4, and leveling assemblies are arranged on the side walls of the clamping plates 2 away from the guide rail main body 1.

[0027] As shown in Figure 1 and Figure 5 The connecting pieces comprise a plurality of studs 7, a plurality of screw holes 9 are formed in the side walls of the guide rail main body 1, the studs 7 are threadedly connected with the screw holes 9, long holes 10 corresponding to the studs 7 are respectively formed in the front and rear side walls of the clamping plates 2, the studs 7 penetrate through the long holes 10, and nuts 8 are threadedly connected with the side walls of the studs 7.

[0028] The leveling assembly comprises a bolt 5 threadedly connected with the side wall of the clamping plate 2, limit holes 6 are respectively formed in the left and right end faces of the guide rail main body 1, and one end of the bolt 5 extends into the limit hole 6.

[0029] The gap is reserved between the stud 7 and the long hole 10 after the stud 7 is inserted into the long hole 10, the nuts 8 can be loosened in subsequent maintenance, the clamping force between the clamping plates 2 and the guide rail main body 1 is reduced, the resistance of the two side bolts 5 to the guide rail main body 1 is adjusted, displacement space is provided for subsequent correction and adjustment of the guide rail main body 1, the effect of efficient leveling is achieved, and the difficulty of subsequent maintenance of the guide rail main body 1 is reduced.

[0030] As shown in Figure 2 The side walls opposite to each other of the two supporting beams 3 are respectively assembled with connecting plates 11, and the two connecting plates 11 are fixedly connected with a reinforcing beam 12. The reinforcing beam 12 can be fixedly connected with the wall of the elevator shaft through screws, expansion bolts and the like, and the length of the reinforcing beam 12 can be selected according to the spacing between the two supporting beams 3, so as to reduce the deformation amount of the two supporting beams 3 in long-term use, further strengthen the supporting strength, and prolong the durability of supporting the guide rail main body 1.
