Description

Technical Field

[0001] The utility model relates to a fixing device, in particular to an elevator guide wheel fixing device. Background Art

[0002] The elevator traction machine is the power equipment of the elevator, also known as the elevator host. Its function is to convey and transmit power to make the elevator run. It consists of an electric motor, a brake, a coupling, a reduction gear, a traction wheel, a frame, a guide wheel, and an auxiliary handwheel. The guide wheel is generally installed on the frame or the load-bearing beam under the frame. The guide wheel is set to make the elevator run more smoothly. During the setting of the guide wheel, the verticality of the guide wheel needs to be ensured, otherwise it will cause the elevator to shake during operation and the steel rope to wear more severely, affecting the comfort and safety of the elevator. Now, after tightening the bolts to lock the guide wheel fixing device, one hand holds the plumb line and the other hand holds the ruler for measurement. If it does not meet the standard, the bolts are loosened and the gaskets are added, and then tightened again for measurement, which has low work efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a guide wheel fixing device, which has the advantage of being convenient for workers to check the verticality of the guide wheel, thereby improving work efficiency.

[0004] The technical solution of the utility model: a guide wheel fixing device comprises a connecting plate connected to the cross beam of the traction machine base, a plurality of groups of slots are arranged on the connecting plate, a lower bracket is arranged on the lower side of the connecting plate through a gasket, a wheel axle for installing the guide wheel is arranged between the lower brackets, a rope stop plate is arranged on the lower side of the wheel axle, a reinforcing plate is arranged on the upper side of the wheel axle, a guide groove in the same direction as the length direction of the reinforcing plate is arranged in the reinforcing plate, a moving block is arranged in the guide groove, a plumb line is arranged under the moving block, and a measuring ruler that can rotate relative to the lower bracket is arranged in the lower bracket.

[0005] In the aforementioned guide wheel fixing device, the lower bracket includes a horizontal plate connected to the connecting plate, a vertical plate perpendicular to the horizontal plate is welded to the lower side of the horizontal plate, the vertical plate is an I-shaped vertical plate in cross-section, a mounting hole for installing the wheel axle is provided in the middle of the vertical plate, and vertically arranged limit grooves are provided at both ends of the vertical plate near the wheel axle.

[0006] In the aforementioned guide wheel fixing device, a locking hole corresponding to the slotted hole is provided in the transverse plate.

[0007] In the aforementioned guide wheel fixing device, the measuring ruler is a telescopic measuring ruler, one end of the measuring ruler is provided with a limit block corresponding to the limit groove, and a leveling bubble is provided in the measuring ruler.

[0008] Compared with the prior art, the utility model improves the supporting effect by arranging a reinforcing plate, and a moving block is arranged in the reinforcing plate, which is convenient for adjustment according to the position of the guide wheel. When the gasket is arranged and the lower bracket and the connecting plate are installed on the cross beam of the traction machine base, the moving block can be moved to make the plumb line contact with the upper end of the guide wheel in a natural state. By adding or removing the gasket, the lower end of the guide wheel can gradually solve the plumb line, thereby playing a role in adjusting the verticality of the guide wheel. The adjustment is convenient. During the test, it is necessary to hold the lower bracket with one hand and hold the measuring ruler with the other hand for measurement. The measurement can be adjusted in real time according to the measurement results to improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0011] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0012] Embodiment. A guide wheel fixing device, comprising: Figure 1 As shown, it includes a connecting plate 1 connected to the cross beam of the traction machine base, a plurality of slots 2 are provided on the connecting plate 1, a lower bracket 4 is provided on the lower side of the connecting plate 1 through a gasket 3, a wheel axle 5 for installing a guide wheel is provided between the lower brackets 4, a rope stopper plate 6 is provided on the lower side of the wheel axle 5, a reinforcing plate 7 is provided on the upper side of the wheel axle 5, a guide groove 8 in the same direction as the length direction of the reinforcing plate 7 is provided in the reinforcing plate 7, a moving block 9 is provided in the guide groove 8, a plumb line 10 is provided under the moving block 9, and a measuring ruler 11 rotatable relative to the lower bracket 4 is provided in the lower bracket 4.

[0013] The lower bracket 4 includes a horizontal plate 12 connected to the connecting plate 1, and a vertical plate 13 perpendicular to the horizontal plate 12 is welded to the lower side of the horizontal plate 12. The vertical plate 13 is an I-shaped vertical plate in the cross-section. A mounting hole 14 for mounting the wheel axle 5 is provided in the middle of the vertical plate 13, and vertically arranged limit grooves 15 are provided at both ends of the vertical plate 13 near the wheel axle 5.

[0014] The transverse plate 12 is provided with a locking hole 18 corresponding to the slot hole 2 .

[0015] The measuring ruler 11 is a telescopic measuring ruler. A limiting block 16 corresponding to the limiting groove 15 is provided at one end of the measuring ruler 11 , and a leveling bubble 17 is provided in the measuring ruler 11 .

[0016] Principle of the utility model: When installing the utility model, the bolts are passed through the connecting plate 1, the gasket 3 and the lower bracket 4 to fix the utility model, and the other end of the bolt is provided with a locking nut. The guide wheel is installed in the utility model through the wheel shaft 5. After installation, the verticality of the guide wheel needs to be measured. At this time, the lower bracket 4 can be changed relative to the crossbeam of the traction machine base by loosening the nut. At this time, the moving block 9 is moved along the guide groove 8, so that the plumb line 10 is in a vertical state and fits with the upper end of the guide wheel. At this time, the lower bracket 4 can be rotated to make the lower end of the guide wheel close to the plumb line 10, and the measurement is performed by the measuring ruler 11. At this time, one hand drags the lower bracket 4, and the other hand rotates the measuring ruler for measurement. The measuring ruler 11 is provided with a leveling bubble 17, so that the detection is more accurate. After the detection determines that the verticality of the guide wheel is qualified, the gasket is adjusted between the connecting plate 1 and the lower bracket 4 so that the lower bracket 4 can be at this angle, that is, the verticality of the guide wheel is qualified. After the installation is completed, the plumb line 10 can be removed from the moving block 9, and the measuring ruler 11 can be removed from the limiting groove 15 to prevent the vibration during the movement of the elevator from affecting the plumb line and the measuring ruler, thereby causing safety hazards.
