Description

Technical Field

[0001] The present invention relates to the technical field of elevator installation, and in particular to an elevator installation device which is convenient for loading and unloading. Background Art

[0002] The elevator serves several specific floors in the building. Its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. The main function of the elevator's guide system is to limit the freedom of movement of the car and counterweight, so that the car and counterweight can only move up and down along the guide rails. The guide system is mainly composed of guide rails, guide shoes and guide rail frames. The elevator guide rails are two or more rows of vertical or inclined rigid tracks installed in the elevator shaft or between floors, ensuring that the car and counterweight move up and down along them, ensuring that the steps of escalators and moving walkways move along them in an inclined or horizontal manner, and providing guidance for the elevator car, counterweight device or steps.

[0003] The elevator guide rail is an elevator component composed of a steel rail and a connecting plate. It is a safety rail for the elevator to travel up and down in the shaft.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] Reference Figure 1-10, an elevator installation device convenient for loading and unloading, comprising an operating table 1, both ends of the operating table 1 are installed with hangers 15, and the top of the hanger 15 is screwed with a lifting ring 14, the four corners of the top of the operating table 1 are provided with installation grooves 10 of strip structure, and the bottom of the installation groove 10 is fixedly installed with a locking mechanism 4, a circular groove 16 is provided in the middle of the top of the operating table 1, and an adjustment mechanism 13 is fixedly installed inside the circular groove 16, and a balancing mechanism 9 is rotatably installed at the bottom end of the outer side of the adjustment mechanism 13, and a movable pin 12 fixedly matched with the outer side of the adjustment mechanism 13 is also installed on the top of the operating table 1, and vertically distributed guide brackets 8 are installed on both sides of the balancing mechanism 9, and the guide brackets 8 are fixedly installed on the outer side of the adjusting mechanism 13. The inner side surface of the guide bracket 8 is provided with two inclined rectangular tubes 17, and the bottom end of the locking mechanism 4 is inserted into the inside of the rectangular tube 17, the outer side surface of the guide bracket 8 is provided with a limiting groove, and the edge of the limiting groove is provided with a limiting protrusion 5, a stopping mechanism 6 is slidably installed between the multiple limiting protrusions 5, and the back of the stopping mechanism 6 is transmission-connected to the bottom end of the locking mechanism 4, connecting grooves are provided above and below the outer side surface of the guide bracket 8, and multiple guide wheel mechanisms 7 are installed inside the connecting grooves, two plug-in guide grooves 11 are provided at the bottom of the operating table 1, and the ends of the two plug-in guide grooves 11 are plug-in installed with guide brackets 3, and the outer side of the guide bracket 3 is slidably installed with a guide rail positioning mechanism 2.

[0031] In the present invention, an operating table 1 is provided which moves up and down inside the elevator shaft through a steel cable. The operating table 1 is connected to the steel cable by a hanger 15 and a lifting ring 14. Guide brackets 8, a stopper mechanism 6, a locking mechanism 4 and a balancing mechanism 9 which are assembled and fixed are provided at both ends of the operating table 1. When it is necessary to stay in the elevator shaft for a long time for operation, the guide bracket 8, the stopper mechanism 6, the locking mechanism 4 and the balancing mechanism 9 can be installed on the operating table 1. The spacing between the guide brackets 8 at both ends can be adjusted according to the width inside the elevator shaft. When the adjusting mechanism 13 is in the highest position, the guide wheel mechanism 7 on the guide bracket 8 can roll against the wall of the elevator shaft. When the adjusting mechanism 13 reaches the installation position, the staff presses the adjusting mechanism 13 downward to make it in the lowest position. At the same time, the balancing mechanism 9 is driven to move downward. The guide bracket 8 at the end moves outward synchronously, pressing and fixing the guide wheel mechanism 7 to the elevator shaft wall. At this time, the operating table 1 spans the interior of the elevator shaft to form a stable operating platform, and a stopping mechanism 6 that can move outward is arranged inside the guide bracket 8. The stopping mechanism 6 is affected by the locking mechanism 4 at the bottom end of the operating table 1. When the two ends of the operating table 1 and the elevator shaft wall are in a stopped state, the locking mechanism 4 moves downward under the action of gravity and pushes the stopping mechanism 6 to move outward. The locking mechanism 4, the stopping mechanism 6 and the elevator shaft wall are engaged with each other to complete the gravity self-locking fixation of the operating table 1 on the elevator shaft wall. The installer can limit and fix the hoisted elevator guide rails through the guide rail positioning mechanism 2 to avoid shaking during the installation of the elevator guide rails, thereby improving the safety and convenience of the elevator guide rail installation.

[0032] As a further solution in the present invention, the locking mechanism 4 includes a main board body 41 arranged at the bottom of the operating table 1, and a mounting bolt 43 fixedly connected to the mounting groove 10 is arranged on the top of the main board body 41, and a movable block 45 which can be adjusted forward and backward is arranged at the bottom of the main board body 41, and a locking bolt 42 plugged and unplugged and connected to the rectangular tube 17 is arranged at the bottom of the movable block 45. In the present invention, the locking mechanism 4 is installed at the bottom of the operating table 1. After the guide bracket 8 is fixedly locked with the wall of the elevator shaft, the tension of the steel cable at the upper end of the device is reduced, and the operating table 1 moves downward under the action of gravity. The locking bolt 42 slides with the rectangular tube 17 and then expands to the two end positions. The end of the locking bolt 42 squeezes the stop mechanism 6 to embed it into the wall of the elevator shaft to complete the secondary self-locking, effectively improving the stability and safety of the device spanning the elevator shaft.

[0033] As a further solution in the present invention, a rectangular guide groove 44 that slides with the movable block 45 is provided at the bottom of the main board body 41, and an adjusting bolt 46 is screwed inside the rectangular guide groove 44, and a sleeve is installed inside the movable block 45 through a spring, and the sleeve is screwed with the adjusting bolt 46. In the present invention, after the operating table 1 is located inside the elevator shaft, the installer can adjust the position of the movable block 45 inside the rectangular guide groove 44 by rotating the adjusting bolt 46, and synchronously adjust the cross-spacing distance at both ends of the balancing mechanism 9 with the adjusting mechanism 13 to quickly adapt to the size of the elevator shaft. The setting of the spring and the sleeve allows the movable block 45 to expand freely outward when under pressure, thereby completing the pushing operation of the stopping mechanism 6.

[0034] As a further solution in the present invention, the stopping mechanism 6 includes a stopping plate 61 that slides with the guide bracket 8, and a plurality of stopping teeth 63 are arranged on the outer side of the stopping plate 61, and a groove 64 that slides with the limiting protrusion 5 is arranged at the edge of the stopping plate 61, and a plurality of tension springs 62 connected with the guide bracket 8 are arranged on the inner side of the stopping plate 61. In the present invention, when the device moves upward, the locking mechanism 4 does not apply thrust to the stopping mechanism 6. At this time, the tension spring 62 drives the stopping plate 61 to retract into the guide bracket 8, so that the device can move upward in the elevator shaft. When the device stops and needs to operate, the locking mechanism 4 moves outward under the action of gravity, pushing the stopping mechanism 6 to move outward, and the stopping teeth 63 on the outer surface of the stopping plate 61 firmly grasp the wall of the elevator shaft, thereby realizing the stable stop operation of the device at the working position, thereby improving the convenience of operation.

[0035] As a further solution in the present invention, the balancing mechanism 9 includes a balancing sleeve 91, and two telescopic rods 92 inserted at both ends of the balancing sleeve 91, and the inner sides of the two telescopic rods 92 are provided with racks 95 meshing with the adjustment mechanism 13, the outer ends of the two telescopic rods 92 are hinged with push-pull rods 94, and the bottom ends of the two push-pull rods 94 are hinged with push plates 93 fixedly connected to the guide bracket 8. In the present invention, after the balancing mechanism 9 is installed, the two push-pull rods 94 can be driven to move outward synchronously by rotating the adjustment mechanism 13, and the push plates 93 and the guide bracket 8 are connected. After the bracket 8 is fixedly connected, when the installer pulls up the adjustment mechanism 13 above the operating table 1, the balancing mechanism 9 can be driven to move upward, and the push-pull rods 94 at both ends can drive the guide bracket 8 to move inward, so that the device can move up and down in the elevator shaft. When it is necessary to stop, the installer moves the adjustment mechanism 13 downward above the operating table 1. When the balancing mechanism 9 moves downward, it pushes the guide bracket 8 to move toward the wall of the elevator shaft. The guide wheel mechanism 7 contacts the wall of the elevator shaft under pressure, and the two ends of the device are preliminarily fixed to complete the fixing operation of the device position.

[0036] As a further solution in the present invention, the adjusting mechanism 13 includes a ring body 135 rotatably mounted in the middle of the balancing sleeve 91, and an annular seat 131 fixedly mounted in the middle of the circular groove 16, and an adjusting gear ring is arranged in the middle of the ring body 135, an adjusting core rod 132 is slidably mounted between the annular seat 131 and the ring body 135, and a positioning slot 133 for snap-fitting is arranged between the adjusting core rod 132 and the annular seat 131, a return spring 136 rotatably connected to the ring body 135 is arranged at the bottom end of the adjusting core rod 132, and brake teeth 134 meshing with the two end positions of the ring body 135 are also arranged at the outer ends of the adjusting core rod 132. In the present invention, when the balancing mechanism 9 needs to be adjusted, the installer pulls the adjusting rod upwards to adjust the balance mechanism 9. The core rod 132 is connected to the adjusting rod 132, and the positioning slot 133 between the adjusting rod 132 and the annular seat 131 is disengaged, and the braking teeth 134 at the lower end of the adjusting rod 132 and the ring body 135 are engaged with each other. Rotating the adjusting rod 132 can drive the ring body 135 to rotate, thereby adjusting the contraction distance between the two push-pull rods 94. When fixing is required, the installer presses down the adjusting rod 132, and the positioning slot 133 between the adjusting rod 132 and the annular seat 131 is engaged and fixed, and the braking teeth 134 at the upper end of the adjusting rod 132 and the ring body 135 are engaged with each other. At the same time, the balancing mechanism 9 is pushed downward as a whole, and the adjusting rod 132 is locked and fixed under the action of the movable pin 12, thereby completing the fixing operation of the guide bracket 8, and the operation is simple and convenient.

[0037] As a further solution in the present invention, the guide wheel mechanism 7 includes a spring rod 72 installed on the guide bracket 8, and a U-shaped seat 71 installed at the front end of the spring rod 72. A guide wheel 74 is rotatably installed in the inner position of the U-shaped seat 71. In the present invention, when the adjustment mechanism 13 lifts the balancing mechanism 9 upward, the guide wheel 74 on the outside of the guide wheel mechanism 7 contacts the wall of the elevator shaft. When the device moves up and down, it rolls with the wall through the guide wheel 74. When the adjustment mechanism 13 presses the balancing mechanism 9 downward, the spring rod 72 contracts to reduce the distance between the stop mechanism 6 and the wall.

[0038] As a further solution in the present invention, the middle part of the spring rod 72 is a hollow structure, and a stop pin 73 is installed inside the spring rod 72, and a plurality of stop grooves 75 compatible with the ends of the stop pin 73 are provided on the outer side of the guide wheel 74. In the present invention, when the spring rod 72 is compressed and contracted, the stop pin 73 located inside the spring rod 72 moves forward, and the stop groove 75 on the surface of the guide wheel 74 cooperates with the stop pin 73 to quickly stop and fix the guide wheel 74, thereby completing the fixation between the two ends and the elevator shaft wall when the operating table 1 stops.

[0039] As a further solution in the present invention, the guide bracket 3 includes a bracket rod 33 which is plugged and unplugged into the two plug-in guide grooves 11, and a track rod 31 is installed at the front end position of the two bracket rods 33, and both ends of the track rod 31 are screwed with positioning screws 32. In the present invention, when the device stays inside the elevator shaft, the guide bracket 3 is pushed forward, and the front end position of the positioning screw 32 is used to contact the guide rail installation wall in the elevator shaft, so as to avoid the elevator guide rail from swinging left and right when the elevator guide rail moves downward to adjust the position in the middle of the guide rail positioning mechanism 2, thereby improving the operational stability when the guide rail end is fixed.

[0040] As a further solution in the present invention, the guide rail positioning mechanism 2 includes a damping slider 21 slidably connected to the track rod 31, and two vertical plates are arranged on the side of the damping slider 21, and the sides of the two vertical plates are screwed with multiple rows of guide rail positioning members 22, and the ends of the guide rail positioning members 22 are rollingly installed with positioning balls 23 rollingly connected to the guide rail surface. In the present invention, when the guide rail is hoisted to the installation position, the installer moves the guide rail positioning mechanism 2 to the interface of the guide rail, and squeezes the guide rail positioning members 22 at the ends of the two guide rails respectively, and aligns the two ends of the guide rail by rotating the guide rail positioning members 22, and effectively fixes the ends of the guide rails, effectively avoiding shaking when the guide rail ends are installed and fixed, providing a stable operating platform for the splicing of the guide rails, and providing a clamp fixing structure for the assembly of the guide rail ends, thereby improving the guide rail installation efficiency.

[0041] When in use, if it is necessary to stay in the elevator shaft for a long time, the guide bracket 8, the stop mechanism 6, the locking mechanism 4 and the balancing mechanism 9 can be installed on the operating table 1. According to the width of the interior of the elevator shaft, the spacing between the guide brackets 8 at both ends is adjusted. When the adjustment mechanism 13 is in the highest position, the guide wheel mechanism 7 on the guide bracket 8 can roll against the wall of the elevator shaft. When it reaches the installation position, the staff presses the adjustment mechanism 13 downward to make it in the lowest position. At the same time, it drives the balancing mechanism 9 to move downward, and the guide brackets 8 at both ends move outward synchronously to press the guide wheel mechanism 7 and the wall of the elevator shaft to fix it. At this time, the operating table 1 spans across the elevator shaft. The interior of the guide bracket 8 constitutes a stable operating platform, and a stopping mechanism 6 that can move outward is arranged inside the guide bracket 8. The stopping mechanism 6 is affected by the locking mechanism 4 at the bottom of the operating table 1. When the two ends of the operating table 1 and the elevator shaft wall are in a stopped state, the locking mechanism 4 moves downward under the action of gravity and pushes the stopping mechanism 6 to move outward. The gravity self-locking fixation of the operating table 1 on the elevator shaft wall is completed by utilizing the engagement between the locking mechanism 4, the stopping mechanism 6 and the elevator shaft wall. The installer can limit and fix the hoisted elevator guide rails through the guide rail positioning mechanism 2 to avoid shaking during the installation of the elevator guide rails, thereby improving the safety and convenience of the installation of the elevator guide rails.
