Problems solved by technology

[0002] The running status of the elevator is directly related to the need for frequent inspections. Minimal changes in the structural performance of each component will have an important impact on the safety and comfort of the ride. During the inspection process, the displacement, distance or Parameters such as deformation, such as the closing distance of the left and right elevator doors in various states, the core depth of the elevator door lock, the distance between the car sill and the landing door sill (also called hall door sill), etc. The measurement is mainly to use a ruler or a tape measure to measure the distance at several positions in the gap. The measurement is not only inconvenient, but also cannot be used for a comprehensive measurement of the entire gap.
In addition, when testing, it should be tested under different loads of the elevator, so that the test results can better reflect the real situation. The current method is to set weights and counterweights in the elevator car to detect the elevator load operation, but currently A large number of heavy inventions are extremely inconvenient to move in the car by manpower

Embodiment 1

[0035] Such as figure 1 , 2 , 3, 4, 5, 6, and 7 show that a kind of elevator safety testing equipment includes a counterweight and a measuring tool, the counterweight includes a weight block 1a as a weight, and also includes a tray 2a for carrying the weight block , the transfer module 3a is arranged on the tray, the transfer module has a rectangular upper surface, the upper surface of the transfer module is embedded with freely rotatable balls 4a, to reduce the moving friction of the weight block thereon Force, the upper surface of the transmission module has a concave edge around the upper surface, that is, the edge is a downward stepped edge 101a, and the concave edges of adjacent transmission modules are adjacent to form slots, thereby forming a vertical and horizontal intersection between the arranged transmission modules. The horizontal slot and the vertical slot, the device includes a horizontal baffle 5a and a longitudinal baffle 6a that can be inserted into the slot,...

Embodiment 2

[0050] Such as Figure 8 , 9 As shown, different from the above-mentioned embodiment, the support spring between the telescopic rod and the sleeve is changed to a tension spring, that is, the two ends of the tension spring are respectively connected to the end of the telescopic rod and the bottom of the sleeve to maintain a gap between the two. A pre-tension force can be used to measure the gap in the vertical state, such as the elevator door gap, as long as the magnetic casters of the left and right brackets are respectively adsorbed on the left and right door panels 14, so that the edge of the turntable is positioned between the left and right door panels Move the support up and down at the gap to make the turntable roll up and down to detect the size change of the gap in the door panel.

[0051] The displacement adjustment device includes axial positioning sleeves 15 fixed on the left and right disk bodies, the axial positioning sleeves have internal threads, and the rotat...

Embodiment 3

[0053] Such as Figure 10 As shown, it also includes an elevator guiding stroke detection device, so as to detect the elevator guiding stroke under various counterweights. The guiding stroke detection device includes a device fixed on the top of the car 1b for detecting the distance between the top of the car and the lowest part of the elevator hoistway top 18b. Displacement sensor 2b, such as a laser rangefinder or other photoelectric distance sensors, when the displacement sensor detects that the car moves upwards, it detects the change information of the distance between the top of the car and the top of the elevator shaft, and also includes a A speed sensor 3b, which detects the speed of the car. The speed sensor can also be fixed on the counterweight 4b. The speed sensor can be a linear speed sensor or an acceleration sensor, as long as it can detect the moment when the speed changes, it can also include a control module, and the control module can adopt an embedded syst...

Abstract

The invention provides elevator safety detection equipment, relates to a tool for elevator detection, and solves the problem in the prior art that elevator detection equipment is inconvenient to use.The elevator safety detection equipment comprises a counterweight and a measuring tool, wherein the measuring tool comprises a rotating shaft; a left disc body and a right disc body are symmetricallyarranged on the rotating shaft, symmetrical in structure, and provided with edges with thin blades; the counterweight comprises trays for bearing weight blocks; conveying modules are arranged on the trays and provided with square upper surfaces; and balls capable of freely rotating are embedded on the upper surfaces of the conveying modules. According to the elevator safety detection equipment, the weight blocks can be moved along the conveying modules by using the trays with ball guide rails, and the friction force is extremely small due to the balls, so that the movement is fast and labor-saving, the weight blocks are convenient to place, and the whole gap width standard can be quickly measured through the simple rolling of the turntables with the conical edges on the gap.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to a tool for elevator detection. Background technique [0002] The running status of the elevator is directly related to the need for frequent inspections.
