Description

Technical Field

[0001] The invention relates to equipment for testing elevator electrical components, in particular to a spray testing equipment for elevator electrical components. Background Art

[0002] Many buttons need to be installed in the elevator car, each corresponding to a floor. Each button is electrically connected to the elevator control box so that the elevator can receive commands from the floor it is running. As the elevator car runs in the elevator shaft, water often enters the top of the elevator shaft, especially in some retrofitted elevator shafts. After water enters, water enters the elevator car and then enters the positions of the various buttons in the elevator car. Therefore, whether the elevator car buttons can still function after water is sprayed on them, that is, the water resistance of the elevator car buttons, is key to the normal operation of the entire elevator and is very important to passengers. Therefore, it is necessary to set up an elevator electrical component spray test equipment to test the water resistance of the elevator car buttons.

[0003] A Chinese patent discloses a method for testing the performance of pure electric vehicle wipers with application number CN202110011510.9. The method includes: testing equipment, which consists of a spray room, a glass mounting stand, an electrical control cabinet and a compression force test bench. The test uses an AC variable frequency motor as the power source, which is driven by a frequency converter and can conveniently adjust the speed. The spray room mechanism consists of a glass frame, a nozzle mechanism, a water receiving tray, a water collection tank, a water pipe, a water pump, and a frequency converter electrical cabinet. The glass mounting stand consists of a glass fixing clamp, a glass mounting stand, a glass pad, a wiper test piece, a soft glass waterproof board, and a sensor bracket.

[0004] While the above method can test wiper performance and determine the wiper's sensitivity after water exposure, it still has the disadvantage that it cannot be installed on elevator car buttons, resulting in the inability to test the performance of elevator car buttons when exposed to water, and unable to guarantee the waterproof performance of elevator car buttons before leaving the factory.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the present invention is further explained below with reference to the accompanying drawings and specific implementation methods.

[0027] like Figures 1 to 5 As shown, the present invention discloses an elevator electrical component spray test device, comprising: a test base 1, a test box 2, a mounting partition 3, an electrical control box (not shown in the figure), an opening and closing valve, a spray pipe 5 and a drainage pipe; the electrical control box is installed in the test base 1, and the test box 2 is installed on the top surface of the test base 1. The top of the test box 2 is open and the test box 2 is made of transparent material. The inner cavity of the test box 2 is separated by the mounting partition 3, one side of the inner cavity of the test box 2 is the mounting cavity, and the other side of the inner cavity of the test box 2 is the test cavity. The elevator electrical component 10 to be tested is installed on the mounting partition 3, the pressing part of the elevator electrical component 10 is located in the test cavity, and the elevator electrical component 10 is connected to the electrical control box through an electric wire 11; a spray pipe 5 is installed on the top of the test cavity, and the water spray port of the spray pipe 5 is directed towards the elevator electrical component 10; a drainage hole is opened and closed by the opening and closing valve, and the drainage hole is connected to the drainage pipe. One end of the elevator electrical component 10 passes through, and the end of the elevator electrical component 10 located in the installation cavity is threadedly connected with a nut to achieve the installation of the elevator electrical component 10.

[0028] The spray pipe 5 is installed on the top of the test box 2 through the mounting bracket 7. The spray pipe 5 is installed on the top of the test chamber.

[0029] The spray pipe 5 is connected to one end of a hose 8, and the other end of the hose 8 is connected to the output end of a water pump (not shown). Water is pumped into the spray pipe 5.

[0030] The mounting frame 7 includes a gantry 71 and positioning bolts 72. The gantry 71 spans the test chamber 2. The bottom of the gantry 71 is recessed to form an insertion slot for the test chamber 2 to be inserted into. The gantry 71 is threadedly connected to the positioning bolts 72, which are pressed against the outer wall of the test chamber 2. By rotating the positioning bolts 72 on the gantry 71, the gantry 71 is positioned on the test chamber 2, preventing the reaction force of the water pressure from pushing the gantry 71 away during spraying.

[0031] The spray pipes include a main spray pipe 51 and branch spray pipes 52. The main spray pipe 51 is mounted on the gantry 71 and connected to the hose 8. The main spray pipe 51 is connected to several branch spray pipes 52. The branch spray pipes 52 are perpendicular to the main spray pipe 51, and the water outlets of the branch spray pipes 52 are directed toward the elevator electrical components 10. The layout of the main spray pipe 51 and the branch spray pipes 52 ensures that the water is sprayed in a divided manner, so that all elevator electrical components 10 on the mounting partition 3 are sprayed with water.

[0032] The end of the spray main pipe 51 is hinged to the gantry 71, and a limited rotation mechanism 9 is installed in the gantry 71. The limited rotation mechanism 9 is used to limit the rotation of the spray main pipe 51. Since the distance between the gantry 71 and the mounting partition 3 is not fixed, in order to ensure that the water droplet spray outlet is directed towards all elevator electrical components 10, the spray main pipe 51 is configured to rotate relative to the gantry 71. This allows the gantry 71 to be placed in any position and the rotation of the spray main pipe 51 to adjust the water droplet spray outlet so that the water droplet is completely directed towards the elevator electrical components 10, ensuring that all elevator electrical components 10 are sprayed with water. Although the hose 8 passes through the top of the gantry 71, the gantry 71 does not restrict the movement of the hose 8, thereby ensuring that the spray main pipe 51 connected to the software can rotate.

[0033] A clamping portion 73 is mounted on the positioning bolt 72. This is used to compress the rotation-limiting mechanism 9 to limit the rotation of the spray main 51. The provision of the clamping portion 73 ensures that when the positioning bolt 72 positions the gantry 71, it simultaneously acts on the rotation-limiting mechanism 9, thereby positioning the spray main 51. Both the gantry 71 and the spray main 51 can be positioned simply by adjusting the positioning bolt 72, improving adjustment efficiency.

[0034] Positioning bolt 72 forms a step 720. A clamping portion 73 is mounted on the side of step 720 near the spray main pipe 51. This clamping portion 73 allows positioning bolt 72 to pass through and does not restrict the rotation of positioning bolt 72. The section of positioning bolt 72 near the spray main pipe 51 has a smaller diameter, while the section farther from the spray main pipe 51 has a larger diameter, thus forming step 720. The section farther from the spray main pipe 51 is threadedly connected to gantry 71, thereby securing the position. The provision of clamping portion 73 enables positioning bolt 72 to push rotation-limiting mechanism 9 to maintain the position of the spray main pipe 51.

[0035] The rotation limiting mechanism 9 includes: a fixed gear ring, a movable gear ring 92 and a movable seat 93. The fixed gear ring is fixed to the spray main pipe 51 and can engage with the movable gear ring 92. The movable gear ring 92 and the movable seat 93 can both move relative to the gantry 71 in the axial direction of the spray main pipe 51. The movable seat 93 is installed on the side of the movable gear ring 92 that backs the spray main pipe 51, and the movable seat 93 is fixed to the clamping part 73.

[0036] An adjustment block 94 is fixed to the mobile gear ring 92. The adjustment block 94 extends through the gantry 71. The gantry 71 has a sliding groove for the adjustment block 94 to move. By moving the adjustment block 94, the gear ring 92 and the movable seat 93 are moved so that the mobile gear ring 92 moves away from the fixed gear ring, and the spray main 51 and the fixed gear ring can be rotated. After the spray main 51 is adjusted into place, the adjustment block 94 is released. Under the elastic force of the positioning spring 95 between the mobile gear ring 92 and the movable seat 93, the mobile gear ring 92 engages with the fixed gear ring, thereby ensuring that the fixed gear ring and the spray main 51 do not rotate automatically. The elastic force of the positioning spring 95 is used to initially position the mobile gear ring 92. When the positioning bolt 72 and the pressing part 73 are subsequently adjusted, the mobile seat 93 fully presses the mobile gear ring 92 through the positioning spring 95, making it unlikely that the positioning spring 95 will deform, thereby ensuring that the position of the mobile gear ring 92 is fully positioned, thereby stably positioning the position of the spray main 51. The movable seat 93 and the movable gear ring 92 cannot rotate relative to the gantry 71 , while the fixed gear ring and the spray main pipe 51 can rotate relative to the gantry 71 together.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
