The following embodiments are used to illustrate the present invention.

[0039] Embodiment 1:

[0040] like Figures 1 to 9 As shown, an elevator guide rail bracket spacing adjustment device includes an adjustment unit 100, a positioning unit 200 and a squeezing unit 300 installed on the elevator shaft wall 500.

[0041] The adjustment unit 100 includes a crossbeam 101, a turntable 103 is rotatably mounted at the center of the crossbeam 101, an adjustment motor 102 is mounted at the rotation center of the turntable 103, and the housing of the adjustment motor 102 is mounted on the side wall of the elevator shaft wall 500, a pair of rocker arms 1032 are rotatably mounted on the turntable 103, the pair of rocker arms 1032 are symmetrically distributed along the rotation center of the turntable 103, a push rod 104 is rotatably mounted at the end of each rocker arm 1032, the push rod 104 is slidably connected to the crossbeam 101, an L-shaped plate 105 is mounted at the end of the push rod 104, and a fixed plate 1055 is mounted at the end of the L-shaped plate 105, L A movable plate 1052 is slidingly arranged on the surface of the L-shaped plate 105, and a guide rail bracket 400 is clamped between the fixed plate 1055 and the movable plate 1052, and the guide rail bracket 400 corresponds to the elevator shaft wall 500; the turntable 103 on the surface is driven to rotate by the adjusting motor 102, and the turntable 103 can drive the position of the rocker arms 1032 at both ends to change, and the rocker arms 1032 push the push rod 104 at the end to slide at the bottom of the beam 101, so that the guide rail bracket 400 clamped by the fixed plate 1055 and the movable plate 1052 on the L-shaped plate 105 moves, thereby achieving the purpose of adjusting the spacing between the guide rail brackets 400.

[0042] The extrusion unit 300 includes two groups of swing arms 301, which are rotatably arranged on the side walls of the fixed plate 1055 and the movable plate 1052 respectively.

After the guide rail bracket 400 is installed, the purpose of automatically completing the fitting operation is achieved, making the operation more convenient, and the fitting operation at this time is completed under the limit operation of the adjustment unit 100, and the fitting position is also more accurate, thereby improving the operating efficiency.

[0045] Embodiment 2:

[0046] The difference between Example 1 and this Example is that: Figures 1 to 9 As shown, a pair of positioning shafts 1033 are installed on the surface of the turntable 103. The pair of positioning shafts 1033 are symmetrical with each other. A ring 1031 is rotatably installed on each positioning shaft 1033. The ring 1031 is connected to a rocker arm 1032, and the rocker arm 1032 is in an inclined state.

[0047] like Figures 1 to 9 As shown, in a specific embodiment, a sliding seat 1041 is installed on the side wall of the push rod 104, a sliding rod 1042 is installed through the inside of the sliding seat 1041, fixed seats 1044 are installed at both ends of the sliding rod 1042, the fixed seat 1044 is installed at the bottom of the beam 101, and a return spring 1043 is sleeved on the sliding rod 1042, one end of the return spring 1043 is clamped on the fixed seat 1044, and the other end is clamped on the surface of the sliding seat 1041. After the push rod 104 moves, the position of the sliding seat 1041 on the side wall of the push rod 104 slides synchronously, and at this time, the sliding seat 1041 slides on the sliding rod 1042 on the surface of the fixed seat 1044, and at the same time, the return spring 1043 on the surface of the sliding rod 1042 is compressed, and the return spring 1043 facilitates the reset operation later.

[0048] like Figures 1 to 9As shown, further, the top of the L-shaped plate 105 is slidably set in the guide groove 1056 opened at the bottom of the beam 101, and the side wall of the L-shaped plate 105 is engaged with a locking bolt 1051, and the end of the locking bolt 1051 is rotatably connected to the movable plate 1052, and a slide rail 1053 is slidably set on the movable plate 1052, and the slide rail 1053 is installed on the L-shaped plate 105, and a plurality of pairs of guide wheels 1054 are rotatably installed on the surface of the movable plate 1052 and the fixed plate 1055, and the rotation direction of the guide wheel 1054 is at a ninety-degree angle with the vertical movement direction of the guide rail bracket 400. Turn the locking bolt 1051, and the locking bolt 1051 moves toward the center of the L-shaped plate 105, driving the movable plate 1052 at the end to move. At this time, the movable plate 1052 slides along the slide rail 1053. At this time, the guide rail bracket 400 can be clamped and fixed by the fixed plate 1055 and the movable plate 1052 to ensure that the guide rail bracket 400 does not slide down. The guide wheel 1054 ensures that the guide rail bracket 400 can move horizontally but not vertically.

[0049] Embodiment 3:

[0050] The difference between Example 2 and this example is that: Figures 1 to 9 As shown, the side wall of the slide plate 201 is provided with an inner groove 2011, and the inner groove 2011 is slidably connected with the cross beam 101. A positioning bolt 2013 is installed through the slide plate 201, and the end of the positioning bolt 2013 is in contact with the surface of the cross beam 101. A notch 202 is provided on the slide plate 201, and a pointer 2021 is installed on the notch 202. The pointer 2021 corresponds to the scale line 2022. The slide plate 201 slides on the cross beam 101, and the scale line 2022 on the surface of the cross beam 101 corresponds to the pointer 2021, so that the position of the slide plate 201 can be accurately controlled. When the position is determined, the operator rotates the positioning bolt 2013 to position the slide plate 201 through the positioning bolt 2013.

[0051] like Figures 1 to 9As shown, in a specific embodiment, a clamping shaft 3011 is movably mounted on the rotation center of the swing arm 301, the clamping shaft 3011 is connected to the side wall of the fixing seat 1044, a torsion spring 3012 is sleeved on the clamping shaft 3011, one end of the torsion spring 3012 is clamped on the swing arm 301, and the other end is clamped on the side wall of the fixing seat 1044, the swing arm 301 is in an inclined state, and the initial state of the swing arm 301 is limited by the torsion spring 3012. A guide seat 3033 is slidably provided on the side wall of the plug rod 303, and the guide seat 3033 is mounted on the swing arm 301, a baffle 3031 is mounted on the plug rod 303, and a limit spring 3032 is sleeved on the plug rod 303 located on the surface of the guide seat 3033 and the baffle 3031, one end of the limit spring 3032 is clamped on the baffle 3031, and the other end of the limit spring 3032 is clamped on the surface of the guide seat 3033. During the continuous rotation of the swing arm 301, the swing arm 301 drives the insertion rod 303 to rotate. At this time, the rotation path of the end of the insertion rod 303 is blocked by the L-shaped plate 105, and the insertion rod 303 will retract along the direction of the swing arm 301, so that the insertion rod 303 slides on the guide seat 3033, and the baffle plate 3031 on the insertion rod 303 forces the guide seat 3033 to be closer, thereby compressing the limit spring 3032 therebetween, and the limit spring 3032 is used to facilitate the subsequent resetting operation.

[0052] like Figures 1 to 9 As shown, further, a positioning slider 3034 is installed at the end of the plug rod 303, and a positioning guide rail 3035 is slidably provided at the end of the positioning slider 3034. The positioning guide rail 3035 is installed on the side wall of the push plate 302. A pressing plate 3023 is fixedly installed on the lower surface of the push plate 302, and an anti-slip groove is provided on the lower surface of the pressing plate 3023. When the plug rod 303 moves, the plug rod 303 pushes the extrusion rod 3022 at the end to move outward. The extrusion rod 3022 slides along the extrusion groove 3021 at this time, and the pressing plate 3023 at the bottom of the extrusion rod 3022 slides downward, and then can be squeezed with the guide rail bracket 400, and push the guide rail bracket 400 to move toward the elevator shaft wall 500, which is convenient for later installation. When the extrusion rod 3022 moves, the positioning slider 3034 at the end of the plug rod 303 can slide on the positioning guide rail 3035, ensuring that the extrusion rod 3022 can slide smoothly.

[0053] The implementation principle of the elevator guide rail bracket spacing adjustment device of the present invention is as follows:

[0054] First, the operator installs the adjustment unit 100 on the elevator shaft wall 500, and the operator disassembles the guide rail bracket 400 that needs to be adjusted, and installs the disassembled guide rail bracket 400 on the L-shaped plate 105. When the guide rail bracket 400 is placed between the fixed plate 1055 and the movable plate 1052, the operator rotates the locking bolt 1051. At this time, the locking bolt 1051 moves toward the center of the L-shaped plate 105, driving the movable plate 1052 at the end to move. At this time, the movable plate 1052 slides along the slide rail 1053. At this time, the guide rail bracket 400 can be clamped and fixed by the fixed plate 1055 and the movable plate 1052 to ensure that the guide rail bracket 400 does not slide down.

[0055] Then the operator can adjust the slide plate 201 , wherein the outer slide plate 201 controls the length of the guide rail bracket 400 moving outward, while the inner slide plate 201 controls the length of the guide rail bracket 400 moving inward.

[0056] At this time, the slide plate 201 can be adjusted according to the required sliding distance, wherein the slide plate 201 slides on the beam 101, and the scale lines 2022 and the pointer 2021 on the surface of the beam 101 correspond to each other, so that the position of the slide plate 201 can be accurately controlled. When the position is determined, the operator turns the positioning bolt 2013 to position the slide plate 201 through the positioning bolt 2013.

[0057] Then the operator starts the adjusting motor 102, and drives the synchronous shaft 1022 connected to the output shaft to rotate on the beam 101 through the adjusting motor 102. A turntable 103 is installed on the side wall of the synchronous shaft 1022, and the turntable 103 can rotate synchronously. When the turntable 103 rotates, the positioning shaft 1033 on the turntable 103 moves, and then the positions of the rocker arm 1032 and the ring 1031 change. A push rod 104 is connected to the end of the rocker arm 1032, and the push rod 104 slides at the bottom of the beam 101.

[0058] After the push rod 104 moves, the position of the slide seat 1041 on the side wall of the push rod 104 slides synchronously. At this time, the slide seat 1041 slides on the slide rod 1042 on the surface of the fixed seat 1044. At the same time, the return spring 1043 on the surface of the slide rod 1042 is compressed, and the return spring 1043 is used to facilitate the subsequent return operation.

[0059] After the push rod 104 moves, the L-shaped plate 105 at the end of the push rod 104 slides on the guide groove 1056, so that the fixed plate 1055 and the movable plate 1052 can move synchronously at this time, and the guide rail bracket 400 clamped by the fixed plate 1055 and the movable plate 1052 begins to move, thereby achieving the purpose of adjusting the spacing between the guide rail brackets 400.

[0060] When the L-shaped plate 105 contacts the slide plate 201, the L-shaped plate 105 is positioned so that the guide rail bracket 400 moves to the specified position. When the L-shaped plate 105 is about to slide to the positioned surface of the slide plate 201, the protrusion 203 on the surface of the slide plate 201 will first contact the swing arm 301. At this time, the swing arm 301 can rotate, and the swing arm 301 drives the push plate 302 at the end to start rotating, so that the push plate 302 slides toward the side of the guide rail bracket 400. However, in the initial stage of sliding, the insertion rod 303 on the side wall of the swing arm 301 will not be squeezed against the side wall of the L-shaped plate 105 at first. When the push plate 302 is about to move to the guide rail bracket 400, the end of the insertion rod 303 will be squeezed against the side wall of the L-shaped plate 105.

[0061] As the swing arm 301 continues to rotate, the swing arm 301 drives the insertion rod 303 to rotate. At this time, the rotation path of the end of the insertion rod 303 is blocked by the L-shaped plate 105, and the insertion rod 303 will retract along the direction of the swing arm 301, so that the insertion rod 303 will slide on the guide seat 3033, and the baffle plate 3031 on the insertion rod 303 forces the guide seat 3033 to be closer, thereby compressing the limit spring 3032 between the two, and the limit spring 3032 is used to facilitate the subsequent reset operation. When the insertion rod 303 moves The insertion rod 303 pushes the extrusion rod 3022 at the end to move outward. The extrusion rod 3022 slides along the extrusion groove 3021 at this time, and the pressure plate 3023 at the bottom of the extrusion rod 3022 slides downward, and then can be squeezed with the guide rail bracket 400, and push the guide rail bracket 400 to move toward the elevator shaft wall 500, which is convenient for later installation. When the extrusion rod 3022 moves, the positioning slider 3034 at the end of the insertion rod 303 can slide on the positioning guide rail 3035, ensuring that the extrusion rod 3022 can slide smoothly.
