Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a positioning structure of an elevator car top guardrail. Background Technique

[0002] The elevator car top guardrail is a protection device used to prevent elevator maintenance personnel from accidentally falling into the hoistway when maintaining the car top. It is a life protection line for elevator maintenance personnel during construction on the car top. According to relevant national standards, when the distance from the inner edge of the hoistway to the outer edge of the guardrail < 850 mm, the height of the guardrail shall not be less than 700 mm; when the distance from the inner edge of the hoistway to the outer edge of the guardrail ≥ 850 mm, the height of the guardrail shall not be less than 1100 mm.

[0003] At present, after the height of the guardrail on the elevator is adjusted, it is usually fixed by multiple bolts. Since the number of bolts is relatively large, it is time-consuming and laborious to loosen and tighten the bolts each time, resulting in low efficiency. In addition, tools matching the bolts are also required, which brings inconvenience to the staff.

[0004] Therefore, we propose a positioning structure of an elevator car top guardrail to solve the problems mentioned above. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned technical problems.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a positioning structure of an elevator car top guardrail, including a fixed guardrail located at the upper part of the elevator body. A plurality of fixing rods are fixed between the elevator body and the fixed guardrail. An adjustable guardrail is arranged on the fixed guardrail. An adjusting rod extending into the fixing rod is fixed on the adjustable guardrail, and a positioning component cooperating with the adjusting rod is installed on the fixing rod.

[0007] Further: The positioning component includes two mounting seats fixed on the side of the fixing rod. The same mounting shaft is fixed between the two mounting seats. A claw is rotatably mounted on the mounting shaft, and a plurality of card slots cooperating with the claw are formed on the side of the fixing rod.

[0008] Further: A torsion spring is sleeved on the mounting shaft, and both ends of the torsion spring are inserted into the interior of the insertion seat. One of the insertion seats is fixed on the inner side wall of the claw, and the other insertion seat is fixed on the outer side wall of the fixing rod.

[0009] Further: Rotating seats are symmetrically fixed on the outer side wall of the claw. The same locking plate is rotatably mounted between the two rotating seats, and a notch cooperating with the locking plate is formed at the upper part of the card slot.

[0010] Further: A number of support plates are equidistantly fixed on the inner side wall of the claw, and when the locking plate rotates along the rotating seat to the horizontal state, the top of the support plate abuts against the bottom of the locking plate.

[0011] Further: A number of fixed cylinders are also equidistantly fixed between the elevator body and the fixed protective rod, and a telescopic rod is slidably installed up and down inside the fixed cylinder, and the top of the telescopic rod penetrates through the fixed protective rod and is fixedly connected to the bottom of the movable protective rod.

[0012] Advantages of the present utility model:

[0013] In the present utility model, a claw is rotatably installed on the fixed rod and a locking plate is rotatably installed on the claw. After the locking plate rotates into the notch, it plays a role in locking the movable protective plate, preventing the movable protective plate from moving downward during use; after the claw rotates into the card slot, it further plays a role in locking the movable fixing plate, preventing the movable fixing plate from moving upward during use, thereby playing a role in fastening the movable protective plate. It can replace the traditional bolt method for fastening. On the one hand, it can quickly fasten the movable protective plate, saving time and effort. On the other hand, no tools are required, thus providing convenience for the staff. Description of the drawings

Detailed implementation manners

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0022] Embodiment of the present invention:

[0023] A positioning structure for an elevator car top guardrail, including an elevator body 1 (the elevator body 1 already belongs to the prior art and will not be described in detail in this application). Two fixing rods 3 are fixed at each corner of the elevator body 1. The tops of the two fixing rods 3 on the same side are fixed with the same fixed guardrail 2. Through the setting of the fixed guardrail 2, it plays a protective role and reduces the phenomenon of falling when the staff works at a high altitude on the elevator body 1. A number of vertical fixing cylinders 7 are fixed between two adjacent fixing rods 3, and the top and bottom ends of the fixing cylinder 7 are respectively fixedly connected to the bottom of the fixed guardrail 2 and the top of the elevator body 1. Through the setting of the fixing cylinder 7, it further plays a protective role and reduces the staff from falling through the gap between the elevator body 1 and the fixed guardrail 2.

[0024] An adjusting rod 5 is slidably installed up and down inside each fixing rod 3. The tops of the plurality of adjusting rods 5 are fixed with the same movable guardrail 4, so that the height of the movable guardrail 4 can be adjusted according to the needs of the user, thereby improving the use effect of the elevator body 1. It should be noted that: a number of telescopic rods 8 are equidistantly fixed at the bottom of the adjusting rod 5, and the bottom ends of the telescopic rods 8 penetrate through the fixed guardrail 2 and are slidably installed inside the fixing cylinder 7.

[0025] It should be noted that: a first through groove is provided on the side wall of the fixing rod 3, and a positioning component 6 is installed at the position of the first through groove. Through the setting of the positioning component 6, it plays a role in locking the adjusting rod 5 and prevents the movable guardrail 4 from shaking up and down during use; <F

[0026] Specifically: The positioning component 6 includes two mounting seats 61 fixed to the side of the fixed rod 3. The same mounting shaft 62 is fixed between the two mounting seats 61. A claw 63 is rotatably mounted on the mounting shaft 62. A plurality of card slots 51 for cooperating with the claw 63 are formed in the side of the adjusting rod 5. When one end of the claw 63 penetrates through the first through slot and is inserted into the interior of one of the card slots 51, it plays a role in limiting the adjusting rod 5 to prevent the movable guard bar 4 from moving upward during use. It should be noted that a torsion spring 64 is sleeved on the mounting shaft 62, and both ends of the torsion spring 64 are respectively inserted into the interior of the insertion seat 65. One of the insertion seats 65 is fixed to the inner side wall of the claw 63, and the other insertion seat 65 is fixed to the outer side wall of the fixed rod 3. Through the setting of the torsion spring 64, it plays a role in pulling the claw 63 to prevent the claw 63 from shaking during use.

[0027] A second through slot is formed in the claw 63, and rotating seats 66 are symmetrically fixed at the position of the second through slot. The same locking plate 67 is rotatably mounted between the two rotating seats 66. A notch 52 for cooperating with the locking plate 67 is formed in the upper part of each card slot 51. When the locking plate 67 rotates into the interior of the notch 52, it further plays a role in locking the adjusting rod 5 to prevent the movable guard bar 4 from moving upward during use. It should be noted that a plurality of support plates 68 are equidistantly fixed to the inner side wall of the claw 63. When the locking plate 67 rotates to a horizontal state with the axis of the rotating seat 66 as the axis, the bottom of the locking plate 67 abuts against the top of the support plate 68, playing a role in supporting the locking plate 67.

[0028] When adjusting the movable guard bar 4 upward, first rotate the locking plate 67 so that the locking plate 67 rotates outside the claw 63 with the axis of the rotating seat 66 as the center, so that the locking plate 67 disengages from the interior of the notch 52. Then, the movable guard bar 4 can be pulled upward, so that the movable guard bar 4 can drive the adjusting rods 5 at both ends to move upward. During the upward movement of the adjusting rod 5, the edges at the top of the plurality of card slots 51 can respectively push the claw 63. When the claw 63 is pushed, it can rotate on the mounting shaft 62 and pull the torsion spring 64, and the torsion spring 64 changes from the original state to the stretched state. When the movable guard bar 4 moves to the specified height, one end of the claw 63 is clamped into the interior of the corresponding card slot 51, thereby playing a role in locking the adjusting rod 5 to prevent the adjusting rod 5 from moving upward during use. Then, the locking plate can be flipped so that the locking plate 67 can rotate into the interior of the corresponding notch 52, further playing a role in locking the adjusting rod 5 to prevent the adjusting rod 5 from moving downward during use.

[0029] When the movable guard bar 4 is adjusted downward, the locking plate 67 is taken out from the inside of the notch 52 in the same way as above, and then the pawl 63 is rotated so that when the pawl 63 disengages from the inner wall of the clamping groove 51, it can drive the movable guard bar 4 to move downward. The two ends of the movable guard bar 4 can respectively drive the adjusting rod 5 to move downward. After the height adjustment of the movable guard bar 4 is completed, the movable guard bar 4 is released, so that one end of the movable guard bar 4 is inserted into the corresponding clamping groove 51, and then the locking plate 67 is inserted into the notch 52 in the same way as above, so as to play a role in fastening the movable guard bar 4 and prevent the movable guard bar 4 from shaking up and down during use.
