DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: It has been found that when the coplanarity of elevator guide rails is detected by using a laser ruler or a level ruler, it is not possible to continuously detect the installed elevator guide rails, which can easily lead to missed detection and false detection. In addition, the above two methods of detecting the guide rails require the staff to climb up in the elevator shaft. The following implementation method is used to solve the above problems.

[0030] A detection device for installing elevator guide rails, referring to Figure 1-Figure 4As shown, it includes a threaded sleeve 1, which is threadedly connected to a threaded rod 2. Anti-slip sleeves are installed on the opposite sides of the threaded sleeve 1 and the threaded rod 2 to facilitate the staff to rotate the threaded sleeve 1 and the threaded rod 2. The threaded sleeve 1 and the threaded rod 2 are rotatably connected to a connecting plate 3. The connecting plate 3 is fixedly connected to two symmetrical telescopic rods 4. The telescopic ends of the two telescopic rods 4 on the same side are commonly fixedly connected to an n-type frame 5. The outer side of the telescopic rod 4 is sleeved with an elastic member fixed to the adjacent connecting plate 3 and the n-type frame 5. The elastic member is set as a spring. Two symmetrical electric wheels 6 are installed on the front and back sides of the n-type frame 5. The elastic member on the outer side of the telescopic rod 4 provides the electric wheel 6 with an extrusion force between the adjacent guide rails. The outer side of the electric wheel 6 is set to a truncated cone shape to adapt to the shape of the elevator guide rail, increase the contact area between the electric wheel 6 and the elevator guide rail, and reduce the collision between the electric wheel 6 and the adjacent guide rail. The sliding situation is improved to improve the stability of the device moving along the guide rail, the n-type frame 5 is slidably connected with a sliding frame 7, an elastic member is fixedly connected between the sliding frame 7 and the adjacent n-type frame 5, the elastic member is set as a spring, and is used to drive the sliding frame 7 to reset, the left and right sliding frames 7 are slidably connected with sliding plates 8 on the opposite sides, and the opposite sides of the two sliding plates 8 are respectively fixedly connected with laser detectors 9 and receivers 10 through mounting seats, the laser detector 9 is used to emit pulsed lasers, and the receiver 10 is used to receive pulsed lasers. The laser detector 9 and the receiver 10 are at the same height, and the receiver 10 is used to receive the pulsed lasers emitted by the laser detector 9 and calculate the offset between the two. The sliding plate 8 is provided with a centering mechanism, and the centering mechanism is used to adjust the position of the sliding plate 8, and the control electric wheel 6 and the receiver 10 are both connected to the external handheld controller signal.

[0031] Reference Figure 4-Figure 6 As shown, the centering mechanism includes a fixed frame 11, which is fixed to the lower end of the adjacent sliding plate 8. The fixed frame 11 is slidably connected with two symmetrical sliding members 12. An elastic member is installed between the fixed frame 11 and the adjacent sliding members 12. The elastic member is a spring, so that the sliding members 12 slide away from each other along the fixed frame 11 at the same time. The outer sides of the sliding members 12 on the left and right sides are both rotatably connected with a rotating sleeve 13. There is a rotation damping between the rotating sleeve 13 and the adjacent sliding member 12, which is used to provide resistance to the rotation of the rotating sleeve 13. When the device moves upward along the guide rail, the rotating sleeve 13 does not rotate along the adjacent sliding member 12. The rotating sleeve 13 is fixedly connected to a one-way bearing 14. The outer ring of the one-way bearing 14 is fixedly connected to a connecting member 15. The connecting member 15 is fixedly connected to a roller 16. When the roller 16 moves upward along the guide rail, the inner ring of the one-way bearing 14 does not rotate. The roller 16 is squeezed and fitted with the adjacent elevator guide rail. An adjustment component is arranged between the sliding plate 8 and the two adjacent sliding members 12. The adjustment component is used to change the distance between the two adjacent sliding members 12.

[0032] Reference Figure 5 and Figure 6As shown, the adjustment component includes a tension spring 17, which is fixed to the outer side of the sliding plate 8 through a mounting plate, the tension of the tension spring 17 is greater than the sum of the elastic forces of the elastic members between the adjacent sliding members 12 and the fixed frame 11, the elastic members between the sliding members 12 and the fixed frame 11 are initially in a force storage state, the sliding plate 8 is provided with a through hole, and a movable plate 18 is limitedly slidably connected in the through hole of the sliding plate 8, the movable plate 18 can only slide up and down along the through hole of the sliding plate 8, the movable plate 18 is fixed to the adjacent tension spring 17, the tension spring 17 is used to pull the movable plate 18 upward so that it moves upward along the through hole of the sliding plate 8, two symmetrical guide wheels are fixed to the lower side of the fixed frame 11, a pull rope 19 is fixed between the movable plate 18 and the two adjacent sliding members 12, the guide wheel is used to guide the pull rope, and the pull rope 19 is wound around the lower side of the adjacent guide wheel.

[0033] When using the device to detect the coplanarity of the installed elevator guide rails, the staff will place the device in an inclined manner between the two guide rails, and then the staff will rotate the threaded sleeve 1 and the threaded rod 2 in opposite directions. At this time, the distance between the threaded sleeve 1 and the threaded rod 2 increases, and the parts on the threaded sleeve 1 and the threaded rod 2 move to the left and right sides respectively, until the electric wheels 6 on the left and right sides are respectively squeezed with the adjacent guide rails, and a certain pressure is maintained between the electric wheels 6 and the adjacent guide rails, and at the same time, the telescopic rod 4 contracts and the elasticity on the outside is compressed. In the above process, taking the parts on the threaded sleeve 1 as an example, the staff pushes the sliding frame 7 to the right, and the sliding frame 7 slides to the right along the n-type frame 5, and the elastic part between the sliding frame 7 and the n-type frame 5 is compressed. At the same time, the staff presses the moving plate 18 downward, and the moving plate 18 slides downward along the through hole of the sliding plate 8, the tension spring 17 is stretched, and the two pull ropes 19 are pulled. The tensioned state is released, and under the action of the elastic member between the sliding member 12 and the fixed frame 11, the two sliding members 12 and the parts thereon are moved away from each other. Then the staff slowly loosens the sliding frame 7, so that the sliding frame 7 drives the sliding plate 8 and the parts thereon to move to the left until the two rollers 16 are located on both sides of the guide rail. Then the staff loosens the moving plate 18, and under the tension of the tension spring 17, the moving plate 18 slides upward along the through hole of the sliding plate 8, and the moving plate 18 pulls the two pull ropes 19 upward, thereby making the two sliding members 12 move closer to each other along the fixed frame 11, and the elastic member between the sliding member 12 and the fixed frame 11 accumulates force again until the two rollers 16 are squeezed on the outside of the guide rail, and then the moving plate 18 stops moving. At this time, the tension spring 17 is still in a stretched state, and then the same operation is performed on the parts on the threaded rod 2, so that the two rollers 16 on the right are also squeezed on the guide rail.

[0034] Then the staff starts the laser detector 9 and the receiver 10 respectively. The laser detector 9 emits a pulse laser, and the receiver 10 receives the pulse laser emitted by the laser detector 9. Initially, the pulse laser emitted by the laser detector 9 is located at the center of the receiver 10. When the position of the pulse laser received by the receiver 10 shifts, the receiver 10 sends a signal to the handheld controller to remind the staff that the two guide rails are not coplanar.

[0035] The staff starts the electric wheels 6 on the left and right sides through the handheld controller, and the electric wheels 6 on the left and right sides drive the device to move upward steadily along the two guide rails. Under the action of the electric wheels 6 on the left and right sides, the threaded sleeve 1 and the threaded rod 2 and the parts thereon move upward in a vertical state with the guide rails. Take the parts on the threaded sleeve 1 as an example:

[0036] The two rollers 16 roll along the guide rail, and the rollers 16 drive the connecting piece 15 thereon to rotate, and the connecting piece 15 drives the outer ring of the adjacent one-way bearing 14 to rotate. When the rollers 16 move upward along the guide rail, the outer ring of the one-way bearing 14 will not drive its inner ring to rotate, and then the rotating sleeve 13 will not rotate along the sliding piece 12. The two rollers 16 move upward in accordance with the guide rail, and the two rollers 16 detect the position of the guide rail in real time. When the guide rails on both sides are not coplanar, the two rollers 16 cooperate with each other to adjust the position of the sliding plate 8. The sliding plate 8 slides along the front and rear directions of the sliding frame 7 according to the positions of the two rollers 16. The sliding plate 8 is coplanar with the adjacent guide rails. When the guide rails on both sides are not coplanar, the pulse laser emitted by the laser detector 9 will deviate from the center position of the receiver 10. At this time, the receiver 10 will emit a signal to the handheld controller and display the offset value on the handheld controller. The staff immediately turns off the electric wheels 6 on the left and right sides, and then the staff calibrates the guide rails here.

[0037] When the guide rails on both sides are calibrated, the staff will continue to detect the coplanarity of the guide rails on both sides according to the above operations. The device moves along the guide rails on both sides through the electric wheels 6 on both sides, so that it can continuously detect and timely detect the coplanarity of the two guide rails, thereby reducing the missed detection and false detection of the guide rails on both sides, and use the laser detector 9 and the receiver 10 to cooperate in detecting the coplanarity of the guide rails on both sides to improve the detection efficiency of the coplanarity of the guide rails on both sides. When the device moves to the uppermost side of the guide rail, the staff will turn off the electric wheels 6 on both sides through the handheld controller, and re-rotate the threaded sleeve 1 and the threaded rod 2 to make the parts on the threaded sleeve 1 and the threaded rod 2 move closer, release the squeezing of the adjacent guide rails by the electric wheels 6 on both sides, and remove the device from the guide rails on both sides and turn off the laser detector 9 and the receiver 10. At the same time, all parts on the device are restored to their initial state.

[0038] Example 2: Based on Example 1, Figure 5 and Figure 6As shown, two extrusion wheels 20 are also included. The extrusion wheels 20 are slidably connected between two adjacent sliding members 12 through a rotating shaft. The opposite surfaces of the two adjacent sliding members 12 are provided with blind holes. The rotating shaft of the extrusion wheel 20 is slidably connected to the two adjacent sliding members 12. Under the elastic force of the elastic member between the adjacent sliding frame 7 and the adjacent n-type frame 5, the extrusion wheel 20 slides upward along the guide rail. The extrusion wheel 20 is extruded and matched with the adjacent elevator guide rail. The extrusion wheel 20 is used to control the distance between the sliding plate 8 and the adjacent elevator guide rail to avoid vibration caused by contact between the sliding plate 8 and the adjacent guide rail.

[0039] Reference Figure 6 As shown, it also includes two symmetrical limit hooks 21, which are respectively fixed to adjacent sliding plates 8. The limit hooks 21 are set to elastic material, and an inclined surface is set on the upper side of the limit hook 21. The movable plate 18 is provided with a through hole. The limit hook 21 is squeezed and limitedly matched with the adjacent movable plate 18. The limit hook 21 passes through the through hole of the movable plate 18, so that the limit hook 21 and the upper side surface of the movable plate 18 are limited, so that the tension spring 17 remains in a stretched state.

[0040] When the staff installs the device between the guide rails on both sides, the staff presses down the movable plates 18 on the left and right sides in turn. Take the movable plate 18 on the left side as an example:

[0041] When the movable plate 18 moves downward, the lower side of the movable plate 18 will squeeze the upper inclined surface of the limit hook 21. The limit hook 21 will be deformed after being squeezed, and then the limit hook 21 will pass through the through hole of the movable plate 18. The limit hook 21 will recover under the action of its own elastic force. At this time, the limit hook 21 and the upper side of the movable plate 18 are limited and matched. When the staff releases the movable plate 18, the movable plate 18 cannot be reset, and the tension spring 17 remains in a stretched state. When the movable plate 18 moves downward, the two sliding members 12 also move away from each other under the action of the elastic member and maintain a certain distance. The limit hook 21 is used to limit the adjacent movable plates 18, and then when installing the device, the two rollers 16 are in a separated state, thereby improving the convenience of installing the device between the guide rails on both sides. In the process of the two sliding members 12 moving away from each other, the rotating shaft of the extrusion wheel 20 slides relative to the two sliding members 12, and the extrusion wheel 20 is still located between the two sliding members 12.

[0042] The staff repeats the above operation to squeeze the electric wheels 6 on both sides onto the adjacent guide rails. When the staff releases the sliding frame 7, under the action of the elastic member between the sliding frame 7 and the n-type frame 5, the sliding frame 7 drives the sliding plate 8 and the parts thereon to move close to the adjacent guide rails, and then the extrusion wheel 20 is pressed against the guide rail. Then the staff pushes the limit hook 21 to release the limit between the limit hook 21 and the adjacent moving plate 18. Then, under the action of the tension of the tension spring 17, the front and rear adjacent rollers 16 are squeezed onto the front and rear sides of the guide rail. When the device moves upward along the guide rail, the extrusion wheel 20 rotates along the guide rail, and the friction between the guide rail and the two adjacent sliding parts 12 is overcome by the extrusion wheel 20, thereby improving the stability of the laser detector 9 in emitting pulsed lasers.

[0043] Example 3: Based on Example 2, refer to Figure 7 and Figure 8 As shown, it also includes four escapement wheels 22 distributed in a rectangular shape. The four escapement wheels 22 are respectively fixed to adjacent rotating sleeves 13. The escapement wheel 22 is located between adjacent sliding members 12 and adjacent connecting members 15. The sliding member 12 is rotatably connected to two symmetrical cava pendulums 23. The cava pendulums 23 are limitedly matched with adjacent escapement wheels 22. The escapement wheel 22 cooperates with the two adjacent cava pendulums 23 to reduce the rotation speed of the escapement wheel 22 by the escapement principle.

[0044] Reference Figure 7 and Figure 8 As shown, it also includes four support shafts 24 distributed in a rectangular shape, and the four support shafts 24 are rotatably connected to the middle parts of adjacent rotating sleeves 13 respectively. One end of the support shaft 24 is fixedly connected to the adjacent sliding member 12 through a mounting plate, and the support shaft 24 does not rotate in the rotating sleeve 13. The other end of the support shaft 24 is rotatably connected to the adjacent roller 16, and the support shaft 24 plays a role in supporting the adjacent roller 16. A centrifugal locking structure 25 is provided between the support shaft 24 and the adjacent rotating sleeve 13. The centrifugal locking structure 25 is an existing structure and is not specifically shown in the accompanying drawings. The centrifugal locking structure 25 includes a limited The limiting circular shell, the fixed disk and the centrifugal column are fixedly connected. The limiting circular shell is fixedly connected to the support shaft 24, the fixed disk is fixedly connected to the rotating sleeve 13, the fixed disk is located in the limiting circular shell, the fixed disk is provided with circumferentially distributed blind holes, the blind holes of the fixed disk are equipped with centrifugal columns that cooperate with the inner wall of the limiting circular shell, an elastic member is installed between the centrifugal column and the fixed disk, the centrifugal locking structure 25 detects the rotation speed of the adjacent roller 16 and locks the adjacent rotating sleeve 13. When the roller 16 drives the rotating sleeve 13 to rotate too fast, the centrifugal locking structure 25 is triggered under the action of centrifugal force, thereby stopping the relative rotation of the rotating sleeve 13 and the support shaft 24.

[0045] When the device moves upward along the guide rail, when the power of the electric wheel 6 is lost or slips, the device moves downward along the guide rail and rotates in the opposite direction, and the roller 16 rotates in the opposite direction along the guide rail. The roller 16 drives the rotating sleeve 13 to rotate synchronously through the one-way bearing 14, and the rotating sleeve 13 rotates along the sliding member 12. The rotating sleeve 13 drives the escapement wheel 22 thereon to rotate, and the escapement wheel 22 rotates circumferentially and cooperates with the two adjacent slip pendulums 23. The two slip pendulums 23 affect the circumferential rotation of the escapement wheel 22 (escapement principle), so that the escapement wheel 22 rotates slowly, reducing the rotation speed of the rotating sleeve 13 and the roller 16, and realizing the slow movement of the roller 16 along the guide rail, thereby improving the safety of the device, and the device slowly moves down along the guide rail to the bottom of the guide rail, which is convenient for the staff to inspect and repair the device.

[0046] When the roller 16 rotates too fast, the rotating sleeve 13 drives the fixed disk and the centrifugal column thereon to rotate under the action of centrifugal force, causing the centrifugal column to move outward, and the elastic member between the centrifugal column and the fixed disk is stretched. When the centrifugal column contacts the inner wall of the limiting circular shell, the limiting circular shell prevents the centrifugal column from continuing to rotate in the circumferential direction, so that the fixed disk and the rotating sleeve 13 stop rotating, and the outer ring of the one-way bearing 14 cannot continue to rotate along the inner ring, thereby performing emergency locking on the roller 16, and utilizing the friction between the roller 16 and the guide rail to stop the device, thereby preventing the device from falling quickly and causing damage, thereby improving the safety of the device.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
