Description

Technical Field

[0001] This utility model relates to the field of elevator car assembly technology, and in particular to an elevator car assembly platform. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves on at least two rigid tracks that are perpendicular to the horizontal plane or have an angle of inclination of less than 15° to the vertical. It is used to vertically transport people and goods to improve the connectivity and efficiency of building spaces.

[0003] An elevator consists of a car, a traction system, and a door system. Elevator installation needs to be carried out in the shaft, where the space is narrow and long. It is very inconvenient to install the elevator car assembly platform in the shaft. It is very difficult to keep the position of the existing elevator car assembly platform used to place the bottom of the car in a horizontal position during installation. After the elevator car assembly platform is installed, the position of the existing assembly platform used to place the bottom of the car cannot be adjusted. It is quite troublesome to measure and adjust the horizontal position of the bottom of the car after it is placed in the elevator shaft, which seriously affects the elevator car installation progress. Utility Model Content

[0004] The purpose of this invention is to provide an elevator car assembly platform that improves the elevator car installation progress.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an elevator car assembly platform, including a base, several support seats are fixed on the upper side of the base, a plate is hinged to the upper end of the support seat and the middle part of the plate is connected to the support seat, and telescopic members that abut against the upper side of the base are fixed at symmetrical positions at both ends of the lower side of the plate, and abutting members are symmetrically arranged at positions near both ends of the upper side of the plate.

[0006] By adopting the above technical solution, after the base is installed in the shaft, the two telescopic components on the lower side of the plate are in the same position and state, and the two abutting components on the upper side of the plate are also in the same position and state. In this way, the plate will be in a relatively horizontal state. Adjust the telescopic component at one end of the lower side of the plate so that it abuts against the upper side of the base. Place the level in the middle of the upper side of the plate, and adjust the telescopic component at the other end of the lower side of the plate according to the level measurement to make the plate horizontal and press against the upper side of the base. Ensure that the plate is in a horizontal state. Place the car bottom on several plates, so that the abutting components of the plates press against the side wall of the car bottom, and fix the car bottom on the plates. With the car bottom placed on the plates in a horizontal position and fixed, it is convenient for the car to be installed, thereby improving the installation progress of the elevator car.

[0007] A further feature of this invention is that the telescopic member includes a first rod fixed vertically to the lower side of the flat plate and a second rod sleeved on the first rod. Both the first rod and the second rod are perpendicular to the flat plate. The first rod is provided with a locking component, and the locking component can fix the second rod to the first rod when the second rod rotates around the first rod.

[0008] By adopting the above technical solution, when adjusting the telescopic component, the second rod moves on the first rod. When adjusted to the appropriate position, the second rod is rotated so that the locking component fixes the second rod on the first rod, making the operation very convenient.

[0009] A further feature of this invention is that the locking assembly includes a first annular plate fixed to the end of the first rod away from the flat plate. The first annular plate has a strip-shaped through groove extending radially from its inner wall to its outer side on the side away from the first rod, and a second annular plate concentrically connected to it. A strip-shaped slider is provided in the strip-shaped through groove, and a protrusion is provided on one side of the strip-shaped slider. An arc-shaped groove extending from the center to the edge is provided on the second annular plate, and the protrusion is embedded in the arc-shaped groove. The center of the first annular plate and the center of the second annular plate are both located on the central axis of the first rod. The edge of the second annular plate has a protrusion, and the inner side of the second rod has a strip-shaped sliding groove extending along its length direction for the protrusion to be embedded in.

[0010] By adopting the above technical solution, since the second annular plate is provided with protrusions, rotating the second rod can drive the second annular plate to rotate. During this process, the protrusions move in the arc groove, thereby driving the strip slider to move in the strip through groove until it abuts against the inner wall of the second rod, thus fixing the second rod on the first rod. This can be completed by one worker, which is convenient for workers to complete in narrow shafts.

[0011] A further feature of this invention is that the length of the strip slider is equal to the outer diameter of the first annular plate. A strip-shaped elongated hole is provided on the outer side of the second rod body, penetrating the inner side and extending along its length. An insert rod perpendicular to the second rod body is inserted through the strip-shaped elongated hole. One end of the insert rod extends out of the strip-shaped elongated hole and is located on the outer side of the second rod body. The other end of the insert rod has a plug-in portion that bends and extends toward the center of the second annular plate and can be inserted into the center position of both the first and second annular plates. A telescopic spring is sleeved on the plug-in portion. The two ends of the telescopic spring are respectively fixed to the outer side of the plug-in portion and the side of the second annular plate away from the first annular plate.

[0012] By adopting the above technical solution, when the second rod rotates and drives the second annular plate to rotate, the strip slider will move away from the center position of the first annular plate. At this time, the insertion rod enters the center of the second annular plate and the first annular plate under the action of the telescopic spring, which can prevent the second rod from returning to its original position.

[0013] A further feature of this invention is that a handle is fixed to one end of the insertion rod located on the outside of the second rod body.

[0014] By adopting the above technical solution, the staff can easily move the insertion rod within the elongated hole of the second rod by holding the handle, which facilitates the release of the fixed relationship between the second rod and the first rod.

[0015] A further feature of this invention is that the abutting member includes a vertical plate fixed to the upper side of the flat plate, the vertical plate being perpendicular to the flat plate, a screw hole being provided on the vertical plate, and an abutting rod being screwed into the screw hole, the abutting rod being perpendicular to the vertical plate.

[0016] By adopting the above technical solution, the abutment component has a simple structure, and operation is very convenient as long as the abutment rod is rotated.

[0017] A further feature of this invention is that: on one of the two abutting rods on a flat plate, a turntable is fixed at the ends of the two abutting rods that are far apart, so as to facilitate the rotation of the abutting rods.

[0018] By adopting the above technical solution, a turntable is set up to facilitate the rotation of the contact rod by the staff.

[0019] A further feature of this invention is that the number of the flat plates is four, and the base has four pedals near the edge that correspond one-to-one with the flat plates.

[0020] By adopting the above technical solution, a footboard is set up to facilitate workers standing on it, making it easier for workers to install the elevator car in the shaft.

[0021] The beneficial effects of this utility model are:

[0022] 1. A flat plate is set on the base for placing the car bottom. Before placing the car bottom, the position of the flat plate is adjusted by a level and the telescopic component to make the flat plate level. Since the hoistway is long and narrow, it is very inconvenient for workers to work in it. It is very difficult to install the base in the hoistway to make the position of the car bottom level. This assembly platform can make the platform for placing the car bottom level, reducing the difficulty of car installation and increasing the speed of elevator car installation.

[0023] 2. Two abutment pieces are symmetrically arranged on the upper side of each plate to abut against the bottom side wall of the car located on the platform, preventing the bottom of the car from shifting during installation and facilitating the installation of the car.

[0024] 3. When adjusting the level of the plate, the second rod moves on the first rod, and the second rod is rotated to drive the second annular plate to rotate, which in turn drives the strip slider to move in the strip groove until one end abuts against the inner wall of the second rod. Under the action of the telescopic spring, the insertion part of the insertion rod is inserted into the center of the second annular plate and the center of the first annular plate, so that the second rod is fixed on the first rod, thereby making the plate level and providing favorable conditions for the installation of the elevator car.

[0031] Example: An elevator car assembly platform, such as Figure 1 As shown, the device includes a base 1, several support seats 2 fixed to the upper side of the base 1, and several flat plates 3 hinged to the upper end of the support seats 2. There are four flat plates 3. The base 1 has four pedals 8 near the edge that correspond one-to-one with the flat plates 3. The middle part of the flat plate 3 is hinged to the upper end of the corresponding support seat 2. Telescopic components 4 are fixed at symmetrical positions at both ends of the lower side of the flat plate 3. The telescopic component 4 includes a first rod 41 vertically fixed to the lower side of the flat plate 3 and a second rod 42 sleeved on the first rod 41. The first rod 41 and the second rod 42 are both perpendicular to the flat plate 3. The first rod 41 is provided with a locking component 43. When the second rod 42 rotates around the first rod 41, the locking component 43 can fix the second rod 42 to the first rod 41.

[0032] like Figures 1 to 4 As shown, the locking assembly 43 includes a first annular plate 431 and a second annular plate 432. The first annular plate 431 is fixed to the end of the first rod 41 away from the flat plate 3. A strip-shaped through groove 431a is formed on the side of the first annular plate 431 away from the first rod 41, extending from the inner wall of the first annular plate 431 through its outer side. A strip-shaped slider 433 is provided in the strip-shaped groove 421, the length of which is the same as the outer diameter of the first annular plate 431. The second annular plate 432 is rotatably connected to the side of the first annular plate 431 away from the first rod 41. The first annular plate 431 and the second annular plate 432 are concentrically arranged, with their centers located on the central axis of the first rod 41. The strip-shaped slider 433 has a protrusion 433a. An arc-shaped groove 432a is formed on the second annular plate 432, extending from the position of the second annular plate 432 near its inner wall to the second annular plate 432. 2. Near the edge, a protrusion 433a is embedded in an arc-shaped groove 432a. The edge of the second annular plate 432 has a protrusion 432b. A strip-shaped groove 421 for the protrusion 432b to be embedded is formed on the inner wall of the second rod 42. The strip-shaped groove 421 extends along the length of the second rod 42. A strip-shaped elongated hole 422 penetrating the inner wall is formed on the outer side of the second rod 42. The strip-shaped elongated hole 422 extends along the length of the second rod 42. A rod 4 is inserted into the strip-shaped elongated hole 422. 34. The insertion rod 434 is perpendicular to the second rod body 42. One end of the insertion rod 434 extends out of the elongated hole 422 and is located outside the second rod body 42, and a handle 6 is fixed at this end. The other end of the insertion rod 434 has an insertion part 434a that bends and extends toward the center of the second annular plate 432. A telescopic spring 435 is sleeved on the insertion part 434a. The two ends of the telescopic spring 435 are respectively fixed on the insertion part 434a and the side of the second annular plate 432 away from the first annular plate 431.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, abutment members 5 are symmetrically provided on the upper side of the plate 3 near both ends. The abutment member 5 includes a vertical plate 51 fixed at one end of the upper side of the plate 3. The vertical plate 51 is perpendicular to the plate 3. A screw hole 511 is provided on the vertical plate 51. An abutment rod 52 is screwed into the screw hole 511. The abutment rod 52 is perpendicular to the vertical plate. A turntable 7 is fixed at the two abutment rods 52 on each plate 3 at the ends that are far apart. The turntable 7 is provided to facilitate the rotation of the abutment rod 52.

[0034] Working principle: A flat plate 3 is set on the base 1 to place the bottom of the car. Using a level, the position of the flat plate 3 is adjusted by the telescopic component 4 to make the flat plate 3 horizontal. When adjusting the flat plate 3 to be horizontal, the second rod 42 moves on the first rod 41. Rotating the second rod 42 causes the second annular plate 432 to rotate, which in turn drives the strip slider 433 to move in the strip groove 431a until one end abuts against the inner wall of the second rod 42. Under the action of the telescopic spring 435, the insertion rod 434 inserts the insertion part 434a into the center of the second annular plate 432 and the first annular plate 41. Center 31, fix the second rod 42 on the first rod 41. When the plate 3 is in a horizontal state, place the bottom of the car on the plate 3 to provide favorable conditions for the installation of the elevator car. Hold the handle 6 to move the insertion rod 434 along the strip-shaped hole 422 so that the insertion part 434a of the insertion rod 434 is away from the center of the first annular plate 431 and the second annular plate 432. Then rotate the second rod 42 until it drives the strip-shaped slider 433 to move back into position in the strip-shaped through groove 431a of the first annular plate 431, thereby releasing the fixed relationship between the second rod 42 and the first rod 41.

[0035] When the flat plate 3 is in a horizontal position, after placing the car bottom on the flat plate 3, hold the turntable 7 to rotate the abutment rod 52 so that the abutment rod 52 is pressed against the side wall of the car bottom, preventing the car bottom from shifting during installation and facilitating the installation of the car.
