Technical field:
This practical tightening device relate to compensating rope of elevator system a part, be particularly related to high-speed elevator compensation rope tension device.
Background technology:
At present, when lifting height of lift arrives to a certain degree or when elevator speed surpasses 2.5M/S, using compensation chain can not meet operating needs, need to use steel rope by way of compensation, this kind of steel rope is called compensation rope, and this compensation rope is walked around the compensation rope pulley that is positioned at hoistway bottom.But the problems such as in high building, owing to being subject to the impact of various factors, this steel rope there will be vibration, rocks, winding, these problems are having a strong impact on the safe in operation of elevator, make troubles to the passenger who takes elevator, or even potential safety hazard; Although the prior art patent No. is 201020681452.8, a kind of high-speed elevator compensation rope tension device is disclosed, comprise fixed guide, travel(l)ing rest, clump weight, safety switch and tension wheel; It will compensate rope and keep tensioning state by utilizing clump weight deadweight to make the travel(l)ing rest tendency toward sliding that keeps down, realizing, the compensation problems such as appearance vibration, winding of restricting while effectively solving elevator high-speed cruising; But this kind of structure deposited following not foot point: 1. because needs configure clump weight, on clump weight fixed support, long-time use easily causes deformation of timbering, and needs to increase purchase clump weight cost; 2. owing to there is no corresponding anti-bouncing device, during elevator high-speed cruising easily there is shaking phenomenon in compensation rope.
Utility model content:
The utility model is for the problem in background technology, proposes a kind of high-speed elevator compensation rope tension device, and its floor area is little, and cost is low, simple in structure, also can effectively solve the problems such as compensation rope easily vibrates, rocks when elevator moves, winding.
The utility model is for solving above technical matters, adopt following technical scheme: a kind of high-speed elevator compensation rope tension device, comprise guide rail, guar plate and the tension wheel of restricting for guiding compensation, guide rail is vertically arranged in hoistway, it is characterized in that: tension wheel is located in guar plate, anti-bouncing device is bolted on guar plate, and two of anti-bouncing device slides up and down at guide rail by shoe guide respectively.
As optimization of the present utility model, described anti-bouncing device comprises support, clamping plate, cushion blocking, and support head both sides are equipped with clamping plate, and clamping plate side is equipped with fixedly shoe guide of bolt; Cushion blocking is located on support, is secured by bolts on guar plate.
As optimization of the present utility model, described guar plate comprises guar plate, side protective plate, and fixation side guar plate is distinguished by bolt in the both sides of upper guar plate, and the centre of both sides side protective plate is provided with wheel shaft, and tension wheel is fixed on wheel shaft.
As optimization of the present utility model, the top of described guar plate is also provided with safe touch switch, and it is fixed on switch installation board.
The utility model adopts above technical scheme, compared with prior art has following technique effect:
One, owing to having reduced clump weight, the weight of deadweight, anti-bouncing device and guar plate by tension wheel, this device is freely moved up and down with guide rail, realize will compensate rope and keep tensioning state, thereby effectively solve elevator, when high-speed cruising, compensate the problems such as the appearance of restricting is vibrated, rocked, winding; And by being provided with safety switch, prevent from compensating the generation of the abnormal condition such as pine or elevator emergency acceleration of restricting, thus guarantee lift running safety, improve the quality that passenger takes elevator.
Two, owing to having reduced clump weight and having increased anti-bouncing device, the floor area that has reduced this device is little, has reduced cost low, and simple in structure.

In Fig. 1-4,1-guide rail, 2-shoe guide, 3-anti-bouncing device, 4-tension wheel, 5-guar plate, 6-wheel shaft, the safe touch switch of 7-, 8-switch installation board, 31-support, 32-clamping plate, 33-cushion blocking, 51-guar plate, 52-side protective plate.
The specific embodiment:
As shown in accompanying drawing 1,2,3,4, in this specific embodiment, the utility model provides a kind of high-speed elevator compensation rope tension device, comprise guide rail (1), guar plate (5) and the tension wheel (4) of restricting for guiding compensation, guide rail (1) is vertically arranged in hoistway, it is characterized in that: tension wheel (4) is located in guar plate (5), it is upper that anti-bouncing device (3) is bolted on guar plate (5), and two of anti-bouncing device (3) slides up and down at guide rail (1) by shoe guide (2) respectively.
As shown in Figure 3,4, described anti-bouncing device (3) comprises support (31), clamping plate (32), cushion blocking (33), support (31) head both sides are equipped with clamping plate (32), and clamping plate (32) side is equipped with fixedly shoe guide (2) of bolt; It is upper that cushion blocking (33) is located at support (31), is secured by bolts on guar plate (51).
As shown in Figure 1, described guar plate (5) comprises guar plate (51), side protective plate (52), fixation side guar plate (52) is distinguished by bolt in the both sides of upper guar plate (51), the centre of both sides side protective plate (52) is provided with wheel shaft (6), and tension wheel (4) is fixed on wheel shaft (6); The top of described guar plate (5) is also provided with safe touch switch (7), and it is fixed on switch installation board (8).
The utility model in use, as shown in Figure 2, first, is vertically fixed on two fixed guides (1) on the pit of elevator, and the two ends of anti-bouncing device (3) are slidably mounted on fixed guide (1) by shoe guide (2).Then, anti-bouncing device (3) will be fixed on tension wheel (4).Then, make compensation rope walk around tension wheel (4), and compensation rope two ends difference correspondence is connected with car with the counterweight of outside, and finally will outside guar plate (5), cover in tension wheel (4), to guarantee that tension wheel (4) rotates, not affected by external factor.
During work, under the weight of deadweight, anti-bouncing device (3) and guar plate (5) or the effect of compensation rope tension of tension wheel (4), this tension wheel (4) moves up and down, when the self gravitation of tension wheel (4) is greater than compensation rope tension, this tension wheel (4) moves down and makes the tensioning of compensation rope, when the self gravitation of tension wheel (4) is less than compensation rope tension, on this tension wheel (4), moves and make the tensioning of compensation rope.Tension wheel (4) move down or on can correspondence there are abnormal condition in the process of moving: when elevator emergency accelerates to occur abnormal condition, the stretched length of the stretched length of compensation rope in greatest limit or compensation rope is during in minimum limit state, touch safety switch (7), safety switch (7) makes elevator automatically out of service, be convenient to elevator management personnel elevator is overhauled timely and effectively, guarantee that elevator keeps safe operation.
