[0024] The utility model will be further described below by specific embodiments in combination with the drawings.

[0025] Embodiment 1:

[0026] As Figures 1-2 shown, an elevator guide rail support assembly comprises a fixed support 1, a movable support 2 and a fastening assembly one 3.

[0027] The fixed support 1 comprises a shaft connecting part 11 and a horizontal flange 12 connected with the shaft connecting part 11, the shaft connecting part 11 is installed on the shaft wall through expansion screws, the movable support 2 is used for fixing and installing the car guide rail, the horizontal flange 12 is used for the movable support 2 to move thereon, by changing the position of the movable support 2 on the fixed support 1, the relative position of the movable support 2 relative to the shaft connecting part 11 is changed, so that the installation position of the guide rail in the shaft is flexibly adjusted, and the installation efficiency of the guide rail is ensured.

[0028] The fastening assembly one 3 is used for fixing and connecting the movable support 2 on the horizontal flange 12 after the movable support 2 is moved into position, specifically fixing and connecting the two side parts of the movable support 2 on the horizontal flange 12, the fastening assembly one 3 specifically comprises a fastening bolt one and a nut one, in order to cooperate with the installation of the fastening assembly one 3, the two side parts of the movable support 2 are provided with fastening connection holes one 21, and the horizontal flange 12 is provided with adjusting connection holes 14 matched with the fastening connection holes one 21. The movable support 2 specifically comprises a guide rail installation part 22 and a support connecting part 23 connected with the guide rail installation part 22, the guide rail installation part 22 is provided with guide rail connection holes 22-1 used for connecting the guide rail, and the support connecting part 23 is used for being connected with the horizontal flange 12 and is provided with the fastening connection holes one 21.

[0029] These are prior art, so the above is only a brief introduction.

[0030] Unlike the prior art, the horizontal flange 12 of the present embodiment is further provided with a guide rail accommodating opening 13, which is recessed from the side of the horizontal flange 12 away from the shaft connecting portion 11 to the side close to the shaft connecting portion 11, and the width of the guide rail accommodating opening 13 is greater than the width of the guide rail. The portions of the horizontal flange 12 located on both sides of the guide rail accommodating opening 13 are provided with the above-mentioned adjusting connecting holes 14. Since the guide rail accommodating opening 13 can accommodate the guide rail, when the movable bracket 2 is moved on the fixed bracket 1 and adjusted to be closest to the shaft wall or the shaft connecting portion 11, the movable bracket 2 can be completely moved into the coverage range of the horizontal projection of the horizontal flange 12, so as not to protrude laterally from the horizontal flange 12. The width of the entire bracket assembly is limited to the width equal to the width of the horizontal flange 12, so that the entire bracket assembly occupies less shaft when adjusted to the minimum width, thereby meeting the design requirements of the car size. In the prior art, the movable bracket 2 lacks the guide rail accommodating opening 13, and the guide rail can only be located laterally of the horizontal flange 12. The movable bracket 2 cannot be completely moved into the coverage range of the horizontal projection of the horizontal flange 12. Therefore, the entire bracket assembly still has a relatively large shaft occupancy rate when adjusted to the minimum width, which adversely affects the design of the larger car space of the elevator.

[0031] Embodiment 2

[0032] Embodiment 2 also relates to an elevator guide rail bracket assembly, which is a further improvement of the elevator guide rail bracket assembly in Embodiment 1.

[0033] The elevator guide rail bracket assembly in the present embodiment, as shown in Figures 3-5 the drawings, further comprises a reinforcing plate 4, which spans the guide rail accommodating opening 13 and is located on the other side of the horizontal flange 12 relative to the movable bracket 2. The two side portions of the reinforcing plate 4 are respectively connected to the portions of the horizontal flange 12 located on both sides of the guide rail accommodating opening 13, thereby greatly reducing the hidden danger of structural strength deterioration of the horizontal flange 12 due to the opening of the guide rail accommodating opening 13, and ensuring the stability of the bracket assembly and the stability after the installation of the guide rail.

[0034] The portions of the reinforcing plate 4 corresponding to the portions located on both sides of the guide rail accommodating opening 13 are further respectively provided with fastening connecting holes two 41 for the fastening bolts at the corresponding positions to pass through. That is, the fastening assembly one 3 not only fastens the movable bracket 2 and the horizontal flange 12, but also fastens the reinforcing plate 4 and the horizontal flange 12, thereby reducing the amount of use of the fastening assembly one 3 and simplifying the installation, and reducing the opening of the hole positions on the portions of the horizontal flange 12 located on both sides of the guide rail accommodating opening 13 to install the fastening assembly one 3, and reducing the structural damage to the horizontal flange 1.

[0035] The reinforcing plate 4 is provided with a reinforcing groove 42 recessed towards the support connecting portion 23, the reinforcing groove 42 further optimizes the structural strength of the reinforcing plate 4 itself and provides better deformation resistance. The reinforcing groove 42 is in abutment with the support connecting portion 23, and the reinforcing groove 42 and the support connecting portion 23 are connected through the fastening assembly two 5, the fastening assembly two 5 comprises a fastening bolt two and a nut two, and the reinforcing groove 42 and the support connecting portion 23 are provided with a fastening connecting hole three 6 through which the fastening bolt two passes. In this way, the movable support 2 is connected to the overall structure composed of the reinforcing plate 4 and the fixed support 1 through multiple positions, the force generated by the movable support 2 on the overall structure is dispersed everywhere, and is not concentrated at the fastening position of the fastening assembly one 3, thereby improving the deformation resistance of the entire support assembly. The number of the fastening assembly two 5 is one, and the fastening assembly two 5 and the fastening assembly one 3 are in a triangular distribution, so that the stability of the entire support assembly is better.

[0036] The above embodiments only describe the preferred embodiments of the utility model, and do not limit the design concept and scope of the utility model. Various modifications and improvements to the technical solutions of the utility model made by those skilled in the art without departing from the design concept of the utility model shall fall within the protection scope of the utility model, and the technical content of the utility model claimed for protection has been fully recorded in the claims.
