Description

Technical Field

[0001] The invention relates to the field of elevator safety protection device production, in particular to a safe and adjustable elevator traction wheel groove wear detection device. Background Art

[0002] The traction sheave is the rope sheave on the traction machine, also called the traction rope sheave or driving rope sheave; it is the device for transmitting traction power in the elevator, and uses the friction between the traction wire rope and the rope groove on the traction wheel rim to transmit power. During the operation of the traction sheave, the traction sheave has to bear the total weight of the elevator car, the load and the counterweight. Therefore, the wheel groove of the traction sheave, especially the bottom surface of the wheel groove, is subject to friction and extrusion by the wire rope. After a long period of operation, the bottom surface of the wheel groove is prone to greater wear and deformation, which affects the safety of the elevator during operation.

[0003] Existing equipment often uses an ultrasonic probe to scan and detect the cross-section of the traction sheave. Although this can detect the wear of the traction sheave, it is unable to detect the change in the diameter of the wheel groove caused by the overall deformation of the traction sheave.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] like Figure 1 and Figure 4 As shown, a safe and adjustable elevator traction wheel groove wear detection device includes a clamping platform 1, a sliding mounting plate 2 is fixedly installed on the upper end of the clamping platform 1, and front and rear sliding grooves 21 that penetrate the front and rear of the sliding mounting plate 2 are opened on the left and right sides of the sliding mounting plate 2, and a plurality of locking devices 3 are slidably connected in the front and rear sliding grooves 21, and a locking mechanism 4 is fixedly installed on the upper end of the locking device 3, and a detachable detection device 5 is locked in the locking mechanism 4.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, the left and right sides of the clamping platform 1 are provided with clamping installation grooves 11 that penetrate the front and rear of the clamping platform 1, and the clamping installation grooves 11 are provided with clamping devices 6, and the clamping devices 6 include a synchronous gear 61, a clamping tooth plate 62, a clamping plate 63, a locking plate 64 and a locking screw 65.

[0034] It should be noted that, in the process of installing the detection equipment, the clamping device 6 on the clamping table 1 is first used to fix the equipment on the machine platform of the traction machine at a position below the traction wheel. In this process, by rotating the locking screw 65, the locking plate 64 located above and the locking plate 64 located below are brought close to each other, and at the same time, the locking plate 64 drives the clamping tooth plate 62 to move along the clamping installation groove 11 in the vertical direction. Since the clamping tooth plate 62 and the synchronous gear 61 are meshed with each other, the clamping plates 63 are brought close to each other and then clamped on the machine platform of the traction machine. Then, according to the number of wheel grooves of the traction machine, a corresponding number of detection devices 5 are installed on the locking mechanism 4, and the detection devices 5 are moved one by one to the position of the corresponding wheel grooves, and the locking device 3 is used to prevent the detection device 5 from moving along the front and rear sliding grooves 21. At the same time, the detection device 5 can be adjusted in the vertical direction so that the detection device 5 can contact the bottom surface of the wheel groove. Through the above device, the present invention can be fixed to traction machines of different models and the wheel grooves of the traction wheel can be detected.

[0035] like Figure 1 , Figure 4 and Figure 6As shown, the locking device 3 includes a front and rear sliding block 31, a locking block 32 and a locking screw 33. There are two front and rear sliding blocks 31 in a single locking device 3, and they are slidably connected to the front and rear sliding grooves 21 on the left and right sides respectively, and the two front and rear sliding blocks 31 are fixedly connected by a synchronization rod 34. The front and rear sliding blocks 31 are provided with locking grooves 311, and the locking groove 311 on the front and rear sliding block 31 on the left side penetrates the left side of the front and rear sliding block 31, and the locking groove 311 on the front and rear sliding block 31 on the right side penetrates the front and rear sliding block 31 The locking plate 32 is fixedly connected to the upper end of the front and rear sliding blocks 31, and the screw mounting plate 312 on the left and the screw mounting plate 312 on the right are rotatably connected with the locking screw 33. The left and right sides of the locking screw 33 are processed with threads of opposite rotation directions, and the threads on the left and right sides of the locking screw 33 are processed at the sides of the threads of the locking block 32. The left and right sides of the sliding mounting plate 2 are respectively fixedly connected with a locking plate 22 corresponding to the locking block 32.

[0036] It should be noted that in the process of fixing the locking device 3 and the sliding mounting plate 2, the locking device 3 is moved so that the detection device 5 on the locking device 3 corresponds to the position of the wheel groove, and then the locking screw 33 is rotated. The locking screw 33 is threadedly connected with the locking block 32 so that the locking blocks 32 on the left and right sides are moved to the left and right directions respectively until the locking block 32 and the locking plate 22 are locked with each other so that the position of the locking device 3 is fixed.

[0037] like Figure 1 , Figure 4 and Figure 6 As shown, the latch mechanism 4 includes a latch fixing plate 41, a latch plate 42 and a latch spring 43. The latch fixing plate 41 is fixedly mounted on the upper end of the screw mounting plate 312. An embedding groove 411 is respectively provided at the left and right positions of the upper end of the latch fixing plate 41. A latch moving groove 412 is respectively provided at the left and right ends of the embedding groove 411 on the latch fixing plate 41. A first baffle 413 is fixedly mounted on the upper end of the latch moving groove 412 near the embedding groove 411. A latch plate 42 is slidably connected between a baffle 413 and the latch movable groove 412. The latch plate 42 is an L-shaped plate, and the vertical end of the latch plate 42 is blocked at the end of the first baffle 413 away from the embedding groove 411. The horizontal section of the latch plate 42 is inserted into the embedding groove 411. The upper side of one end of the latch plate 42 located at the embedding groove 411 is processed into a slope shape, and a latch spring 43 is fixedly connected between the latch plate 42 and the end of the latch movable groove 412 away from the embedding groove 411.

[0038] like Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, the detection device 5 includes a vertical adjustment mechanism 51 and a detection mechanism 52, and the vertical adjustment mechanism 51 includes a fixed rod 511, a mounting rod 512, a vertical slide rod 513 and a vertical adjustment screw 514. A locking rod 515 is fixedly installed at the position of the lower end of the fixed rod 511 corresponding to the embedding groove 411, and protrusions are processed on the left and right sides of the lower end of the fixed rod 511, and a slope corresponding to the slope on the locking plate 42 is processed at the protrusion position, and the left and right sides of the upper end of the fixed rod 511 are fixedly installed with vertical slide rods 513, and the mounting rod 512 is slidably connected to the vertical slide rod 513 along the vertical direction, and the fixed rod 511 is rotatably connected to the vertical adjustment screw 514, and the vertical adjustment screw 514 is threadedly connected to the mounting rod 512.

[0039] It should be noted that when the detection device 5 is installed on the latch mechanism 4, the locking rod 515 is inserted into the embedding groove 411, and the inclined surface of the protrusion on the locking rod 515 will conflict with the inclined surface on the latch plate 42, so that the latch plate 42 moves to the left and right directions. When the protrusion passes over the latch plate 42, under the rebound action of the latch spring 43, the latch plate 42 returns to its original position, thereby locking the locking rod 515. At the same time, when adjusting the vertical position of the detection mechanism 52, the vertical adjustment screw 514 is rotated to move the installation rod 512 in the vertical direction until the detection mechanism 52 moves to a suitable position.

[0040] like Figure 1 , Figure 3 , Figure 7 and Figure 8As shown, the detection mechanism 52 includes a detection installation box 521, the lower end of the detection installation box 521 is fixedly installed on the installation rod 512, the middle position in the detection installation box 521 is slidably connected with a detection rod 522 in the vertical direction, the lower end of the detection rod 522 and the lower end of the detection installation box 521 are fixedly installed with a detection spring rod 523, a raised block is fixedly installed in the middle of the right side of the detection rod 522, and second baffles 5211 are respectively installed at the upper and lower positions corresponding to the raised block in the detection installation box 521, and the left end of the detection rod 522 is fixedly connected with a driving tooth plate 524, and the edge of the driving tooth plate 524 is meshed with a belt The driving gear 525 is coaxially fixedly connected with an enlarging pulley 526, and the right side of the enlarging pulley 526 is rotatably connected with a reducing pulley 527, the diameter of the enlarging pulley 526 is much larger than the diameter of the reducing pulley 527, the enlarging pulley 526 and the reducing pulley 527 are connected by a transmission belt 528, the front end of the detection installation box 521 is rotatably connected with a reading disk 529, and the reading disk 529 is evenly engraved with scales, the upper end of the detection installation box 521 is fixedly connected with a pointer 5291 corresponding to the position of the reading disk 529, and the reducing pulley 527 and the reading disk 529 are coaxially fixedly connected.

[0041] It should be noted that, in the process of detecting the wheel groove by the detection mechanism 52, the upper end of the detection rod 522 is in contact with the bottom surface of the wheel groove. In the process of the traction wheel rotating, the defects on its surface caused by wear and the change in the diameter of the wheel groove caused by long-term operation will cause resistance to the detection rod 522. Under the joint action of the detection spring rod 523, the detection rod 522 will jump in the vertical direction, and the driving tooth plate 524 fixedly connected to the detection rod 522 will also jump in the vertical direction, driving the tooth plate 524 and the driving gear 525. The mutual meshing causes the driving gear 525 to rotate, and the driving gear 525 drives the wide belt pulley to rotate. The expanding pulley 526 drives the reducing pulley 527 to rotate through the transmission belt 528, and the reducing pulley 527 drives the reading disk 529 to rotate. The wear on the traction wheel surface and the change in the wheel groove diameter are observed according to the change in the value pointed by the pointer 5291 to the reading disk 529. Because the wear and diameter change of the wheel groove are relatively not obvious to the senses, the observation effect can be effectively improved by driving the reducing pulley 527 through the expanding pulley 526.

[0042] like Figure 1 , Figure 7 , Figure 8 and Fig.10As shown, the front end of the reading disk 529 protrudes relative to the detection installation box 521, and the protruding part is symmetrically processed with a groove, and there is a connecting line at the position of the groove to penetrate the reading disk 529, and the detection installation box 521 is respectively installed with a power connection mechanism 7 on the left and right sides of the reading disk 529, and the power connection mechanism 7 includes a power connection rod 71 and a reciprocating spring rod 72, one end of the power connection rod 71 is in contact with the reading disk 529, and the power connection rod 71 is slidably connected to the front end of the detection installation box 521, and the reciprocating spring rod 72 is fixedly connected between the upper and lower ends of the power connection rod 71 and the detection installation box 521, and an alarm 8 is also installed on the detection installation box 521, and the power connection rods 71 ​​on the left and right sides are respectively connected to the alarm 8 through wires.

[0043] It should be noted that when the depression on the wheel groove surface or the change in the wheel groove diameter is too large, the reading disk 529 will rotate to a position where the groove thereon corresponds to the power connecting rod 71, and the power connecting rod 71 will be embedded in the groove on the reading disk 529 under the action of the reciprocating spring rod 72, and the power connecting rod 71 will contact the connecting wire, so that the external power supply is connected under the joint action of the power connecting rod 71 and the connecting wire, and the alarm 8 will make sounds and commands when powered on, attracting the attention of the on-duty personnel.

[0044] like Figure 8 As shown, the upper end of the detection rod 522 is tapered, and a rolling detection bead 5221 is provided on the upper end of the detection rod 522 .

[0045] It should be noted that the upper end of the detection rod 522 is tapered and provided with a rolling detection bead 5221, which can reduce the contact area with the bottom surface of the wheel groove so as to better contact the defects on the wheel groove surface and reduce the wear between the detection rod 522 and the wheel groove.

[0046] like Fig. 9 As shown, a threaded hole is processed on the knob at the lower end of the vertical adjustment screw rod 514 , and a locking bolt 5141 is threadedly connected in the threaded hole. The locking bolt 5141 is threadedly connected to the threaded hole and pressed against the fixing rod 511 .

[0047] It should be noted that in order to prevent the detection mechanism 52 from changing its position in the vertical direction, the vertical adjustment screw 514 is fixed to the fixed rod 511 by a locking bolt 5141, thereby preventing the vertical adjustment screw 514 from rotating, thereby preventing the detection mechanism 52 from changing in the vertical direction.

[0048] The working process of the present invention is to first use the clamping device 6 on the clamping table 1 to fix the equipment on the machine platform of the traction machine at a position below the traction wheel, and then install a corresponding number of detection devices 5 on the locking mechanism 4 according to the number of wheel grooves of the traction machine, and move the detection devices 5 one by one to the position of the corresponding wheel grooves, and use the locking device 3 to prevent the detection device 5 from moving along the front and rear sliding grooves 21. At the same time, the detection device 5 can be adjusted in the vertical direction so that the detection device 5 can contact the bottom surface of the wheel groove. In this process, the observation effect can be effectively improved by driving the shrinking pulley 527 by the enlarged pulley 526. When the depression on the surface of the wheel groove or the change in the diameter of the wheel groove is too large, the alarm 8 is turned on by the electrical connection mechanism 7 to make the alarm 8 sound and issue instructions to attract the attention of the on-duty personnel.

[0049] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0050] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
