Description

Technical Field

[0001] The invention relates to a mounting bracket, in particular to an adjustable buffer mounting bracket. Background Art

[0002] The elevator pit needs to be installed with buffers. If for some reason, when the car or counterweight device exceeds the limit position and bottoms out, the buffer is used as a braking device to absorb or consume the kinetic energy of the car or counterweight device. The buffer needs to be installed at a certain height to ensure the safe operation of the elevator. Concrete piers are usually cast on site as the base for installing buffers. 1. It is inconvenient to cast concrete piers on site; 2. The cast-on-site materials cannot meet the provisions of Article 5.3.2.3 of GB7588-2003: The bottom surface of the pit under the counterweight buffer support (or the counterweight operation area) should be able to withstand a force of 4 times the static load of the counterweight (or counterweight). 3. The height of the concrete pier cannot be adjusted after completion. During the actual installation on site, the buffer height needs to be adjusted to the design requirements. After delivery and use, the elevator wire rope will stretch and the buffer distance will be reduced. The wire rope length or buffer height needs to be adjusted to meet the national standard requirements. Summary of the invention

[0003] The invention aims to solve the problems of inconvenient construction, difficulty in bearing load and inability to adjust height when installing a buffer using a cast concrete pier as a base, and provides an adjustable buffer installation bracket.

[0004] The technical solution adopted by the present invention is as follows:

[0005] An adjustable buffer mounting bracket includes a fixed bracket assembly and an upper assembly, wherein the bottom of the fixed bracket assembly is connected to the bottom of the well, and the top of the upper assembly is connected to the buffer; the fixed bracket assembly is provided with a threaded hole, and the lower end of the upper assembly is provided with a threaded column, the threaded column is connected in the threaded hole and realizes a lifting structure through threaded rotation, and a lower fastening nut is also provided on the threaded column; the upper end of the upper assembly is a plane support structure connected to the buffer, and an operating structure for adjusting the lifting structure is provided on the plane support structure. The mounting bracket is made of metal material or non-metallic material with equal or higher strength, and is designed and manufactured in the factory to meet standard requirements, and no concrete piers need to be cast on site; the mounting bracket is mainly divided into two parts, one part is the upper assembly that can be used to adjust the height, and the other part is the fixed bracket assembly that is used to fix the height, which can be used separately, that is, when the height of the fixed bracket is sufficient and no height increase is required, the buffer only needs to be directly installed on the fixed bracket, or it can be used in combination. The arbitrary height adjustment meets the height adjustment requirements of the buffer mounting bracket on site, and the operation is simple and convenient. It can be matched with a variety of buffers, has strong versatility, is simple to make, and is suitable for mass production.

[0006] Furthermore, the planar support structure includes a support plate, the support plate is fixedly connected to the threaded column, an upper bracket is arranged on the support plate, the upper bracket horizontally covers the top of the support plate, and a buffer connection hole is arranged on the upper bracket; the upper bracket is provided with a guide limit structure; the support plate is provided with an operating structure of the adjustment lifting structure. The upper bracket covers the top of the support plate so that the support plate can rotate freely without affecting the upper bracket.

[0007] Furthermore, the support plate is a polygonal or circular structure, and the operating structure is formed by rotating the polygonal or circular support plate.

[0008] Furthermore, the polygonal or circular side end surface of the support plate is provided with an operating hole to form the operating structure, and the operating hole is a hexagonal hole, a round hole, a square hole, or a special-shaped hole. When the buffer is installed on the buffer mounting bracket, the support plate is rotated by inserting a tool into the hole on the side of the support plate to rotate the support plate so that the threaded column rotates up and down in the threaded hole.

[0009] Furthermore, a cross hole is provided on the top end surface of the support plate to form the operating structure.

[0010] Furthermore, the support plate is a polygonal or circular structure.

[0011] Furthermore, the upper assembly and the fixed bracket assembly are connected via the lower bracket and the upper mounting plate of the fixed bracket, a guide sleeve is provided on the end surface of the lower bracket, and a guide rod is provided on the upper bracket, and the guide rod is inserted into the guide sleeve and passes through the lower bracket and the upper mounting plate of the fixed bracket to form the guide limit structure. The guide rod is used to support the upper bracket to prevent the threaded column from tilting during the rotation process, and the guide sleeve is used to protect the guide rod.

[0012] Furthermore, the support plate is connected to the top of the threaded column. The support plate and the threaded column are connected by welding or casting.

[0013] Furthermore, a lower mounting plate of the fixed bracket is provided at the bottom of the fixed bracket assembly to connect to the bottom of the well, and the four corners of the upper bracket, the lower bracket, the upper mounting plate of the fixed bracket and the lower mounting plate of the fixed bracket are chamfered. The chamfer design prevents workers from being injured by hitting sharp corners during work.

[0014] Furthermore, an operation window is provided at the center of the upper bracket corresponding to the position of the cross hole of the support plate. When the buffer is not installed, the lower fastening nut is loosened with a wrench, and then the cross hole on the support plate is rotated through the operation window of the upper bracket with an electric tool or manually, and the threaded column is rotated in the threaded hole while the support plate is rotated to adjust the height of the buffer mounting bracket.

[0015] The present invention has the following beneficial effects: the buffer mounting bracket does not require the pouring of concrete piers on site, the buffer mounting bracket is safe and reliable, easy to install, and the situation where the pouring of concrete buffer piers on site affects the elevator installation period will not occur. The bracket is mainly divided into two parts, one part can be used to adjust the height, and the other part is a fixed height, which can be used separately or in combination. The height adjustment of the traditional adjustable buffer mounting bracket is formed by superimposing several fixed-height buffer mounting brackets, and some heights cannot be achieved. This mounting bracket does not have this problem, and it can adjust the height arbitrarily according to the actual needs of the site. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0030] Example: Figures 1 to 12 As shown, an adjustable buffer mounting bracket includes a fixed bracket assembly and an upper assembly, wherein the bottom of the fixed bracket assembly is connected to the bottom of the well, and the top of the upper assembly is connected to the buffer; the fixed bracket assembly is provided with a threaded hole, and the lower end of the upper assembly is provided with a threaded column 7, the threaded column 7 is connected in the threaded hole and realizes a lifting structure through threaded rotation, and a lower fastening nut 11 is also provided on the threaded column; the upper end of the upper assembly is a planar support structure connected to the buffer, and an operating structure for adjusting the lifting structure is provided on the planar support structure.

[0031] The planar support structure includes a support plate 9, which is fixedly connected to a threaded column 7. An upper bracket 1 is provided on the support plate 9, and the upper bracket horizontally covers the top of the support plate 9. A buffer connecting hole is provided on the upper bracket 1; the upper bracket 1 is provided with a guide limiting structure; and the support plate 9 is provided with an operating structure for adjusting the lifting structure.

[0032] The threaded column 7 is movably connected to the lower bracket 2 via a lower fastening nut 11 .

[0033] The fixing bracket assembly further comprises a round tube 4 , which is mounted on a mounting plate 5 below the fixing bracket, and a threaded hole is arranged in the round tube 4 .

[0034] The mounting bracket is made of metal material or non-metallic material with equal or higher strength. It is designed and manufactured in the factory to meet standard requirements. There is no need to cast concrete piers on site. The mounting bracket is mainly divided into two parts, one is the upper component that can be used to adjust the height, and the other is the fixed bracket component for fixing the height. They can be used separately, that is, when the height of the fixed bracket is sufficient and no longer needs to be increased, the buffer only needs to be directly installed on the fixed bracket, or they can be used in combination. The height can be adjusted arbitrarily to meet the height adjustment requirements of the buffer mounting bracket on site. It is simple and convenient to operate, can be used with a variety of buffers, has strong versatility, is simple to make, and is suitable for mass production.

[0035] The height adjustment of the traditional adjustable buffer mounting bracket is achieved by stacking several fixed-height buffer mounting brackets. Some heights cannot be achieved. This buffer mounting bracket does not have this problem and can be adjusted arbitrarily according to actual needs on site. Compared with concrete pouring, this buffer mounting bracket is safe and reliable, easy to install, and there will be no situation where the on-site poured concrete buffer pier affects the elevator installation period.

[0036] When the buffer is not installed on the buffer mounting bracket, loosen the lower fastening nut 11 with a wrench, and then use an electric tool or manually to rotate the cross hole on the support plate 9 through the operation window 12 of the upper bracket 1. Since the top of the threaded column 7 is fixedly connected to the bottom of the support plate 9, the threaded column 7 rotates in the round tube 4 while the support plate 9 rotates to adjust the height of the buffer mounting bracket. The upper part of the threaded column 7 is a nut 10. In this bracket, the threaded column 7 is a bolt. The bolt cooperates with the nut. When the threaded column 7 rotates up and down, the guide limit structure also moves up and down to prevent the position of the threaded column 7 from deviating to one side. After the height of the buffer mounting bracket is adjusted, install the disassembled upper bracket 1, and then tighten the lower fastening nut 11 with a wrench.

[0037] The buffer mounting bracket needs to adjust the wire rope length or buffer height when the buffer is installed or after the elevator is delivered for use. When adjusting the buffer height, loosen the lower fastening nut 11 with a wrench, and rotate the support plate 9 by inserting a tool into the hole on the side of the support plate 9 or using a wrench to rotate the support plate 9 to make the threaded column 7 rotate up and down in the round tube 4. When the height of the mounting bracket is adjusted, tighten the lower fastening nut 11.
