Description
Technical Field
[0001] This utility model relates to the field of elevator technology, specifically to a traveling cable fixing bracket in an elevator shaft. Background Technology
[0002] With economic development and social progress, most buildings are equipped with elevators to facilitate people's needs for going up and down stairs and traveling. As a special type of equipment used daily, the elevator's traveling cable is a crucial component of the elevator system. Its main function is to transmit power, signals, and data, enabling the car to move up and down in a controlled manner. Generally, one end of the traveling cable is fixed to the guide rails in the elevator shaft. Elevators with higher floors also require an additional intermediate cable fixing bracket. Generally, different elevator models require different models of traveling cable fixing brackets that match the car bottom cable brackets; otherwise, interference and damage to the traveling cable may occur during elevator operation, leading to elevator malfunction. Having too many different models increases the risk of errors during packaging, hinders mass production, easily leads to waste, and increases production costs.
[0003] See Figure 1 The existing traveling cable brackets need to be adapted to each elevator model, such as ( Figure 1 Scheme A and Scheme B: The guide rail models are different, and the mounting hole spacing of the traveling cable mounting bracket is different. Figure 1 The difference between A1 and the counterweight position leads to... Figure 2 The length of the traveling cable mounting bracket varies depending on the B1 (distance between the center of the traveling cable and the car rail). Since the bracket is installed on the guide rail and the traveling cable is far from the guide rail, thicker and longer steel plates must be used to increase the strength of the bracket, which increases the material cost. Utility Model Content
[0004] The purpose of this utility model is to provide a traveling cable fixing bracket in elevator shafts, which solves the technical problems of existing fixing brackets having strong model specificity, low installation accuracy, and poor space adaptability in actual use.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A mounting bracket for a traveling cable inside an elevator shaft includes:
[0007] A support base plate, which is used to be installed on the inner wall of the shaft;
[0008] A first clamping plate and a second clamping plate are used to form a clamping area for holding the traveling cable. The first clamping plate and the second clamping plate are connected by fasteners.
[0009] Among them, several removable pads are provided between the base plate of the bracket and the first clamping plate, so that the distance between the first clamping plate and the base plate of the bracket can be adjusted.
[0010] Furthermore, mounting holes are provided on the base plate of the support, and the base plate of the support is connected to the inner wall of the shaft by expansion bolts.
[0011] The bracket base plate is symmetrically provided with longitudinal slide rails on both sides, and the pad is slidably placed on the longitudinal slide rails. The end of the longitudinal slide rail is provided with a terminal locking device, which is used to fix the pad and the first clamping plate.
[0012] Furthermore, the pad and the longitudinal slide rail are slidably connected through a slide groove.
[0013] The groove is either T-shaped or dovetail-shaped.
[0014] Furthermore, the pad includes at least one base pad and expandable additional pads;
[0015] Base pad, 8-12mm thick;
[0016] Additional pads, with a thickness of 1-7mm; both the base pads and additional pads slide in conjunction with the longitudinal slide rail.
[0017] Furthermore, the first clamping plate is provided with a guide groove corresponding to the longitudinal slide rail, and the side of the first clamping plate is provided with a threaded hole. The terminal locking device is a locking screw that mates with the threaded hole.
[0018] Furthermore, the first and second clamps are made of plastic, and the first and second clamps are connected by screws.
[0019] Furthermore, the first and second clamps have anti-slip textures on the side that contacts the traveling cable.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] This utility model mainly consists of a bracket base plate, a first clamping plate, and a second clamping plate. During installation, it is fixed as a whole to the inner wall of the elevator shaft, and its installation position matches the car bottom cable. To address the issue of different elevator models having different types of traveling cable mounting brackets in the shaft, such as varying lengths and mounting hole spacings, a traveling cable mounting bracket that can freely match different types of elevators is designed using the space of the elevator shaft inner wall.

[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0037] See Figures 1-5 This embodiment discloses a traveling cable fixing bracket in an elevator shaft, comprising:
[0038] A support base plate 101 is used to be installed on the inner wall 102 of the shaft.
[0039] A first clamping plate 103 and a second clamping plate 104 are formed between the first clamping plate 103 and the second clamping plate 104, forming a clamping area 114 for clamping the traveling cable 105. The first clamping plate 103 and the second clamping plate 104 are connected by fasteners, and the first clamping plate 103 is fixedly connected to the bracket base plate 101.
[0040] This utility model mainly consists of a bracket base plate 101, a first clamping plate 103, and a second clamping plate 104. During installation, it is fixed as a whole to the inner wall of the elevator shaft, and its installation position matches the car bottom cable. To address the issue of different elevator models having varying travel cable 105 mounting brackets (e.g., length, mounting hole spacing 106), a travel cable 105 mounting bracket that can freely match different elevator types is designed using the space of the inner wall 102 of the elevator shaft. This utility model removes the limitation of the variable dimension A1; the center of the travel cable 105 only follows the movement of dimension B1, allowing for free matching of the installation position of different elevator ladder-type cable brackets.
[0041] Furthermore, the support base plate 101 is provided with mounting holes 106, and the support base plate 101 is connected to the inner wall 102 of the shaft by expansion bolts 115. The expansion bolts 115 penetrate the inner wall of the shaft for mechanical anchoring, and a rigid connection is achieved by the expansion force of the bolts.
[0042] like Figure 1 and Figure 2 As shown, Figure 2 Option A is without a machine room, while Option B is with a machine room. Both are implementation methods of the existing 105 traveling cable bracket.
[0043] Depend on Figure 1 It can be seen that the original 105-type traveling cable bracket method must be adapted. Figure 1 The variables A1 (the mounting hole spacing of the mounting bracket for the traveling cable 105) and B1 (the distance between the center of the traveling cable 105 and the car track 113) are specified. Figure 2 Embodiment 1 illustrates this invention, where the influence of variable dimensions A1 and B1 is eliminated, resulting in a universal model. In this invention, the installation position of the traveling cable 105 fixing bracket can be adjusted as needed.
[0044] The traveling cable 105 runs from the machine room or control system into the hoistway, is fixed to the upper end of the hoistway using the existing cable, and then extends the traveling cable 105 to a sufficient length, with its other end fixed to the car bottom cable bracket 112 located at the bottom of the car. The center position of the cable in the hoistway must be aligned with the center position of the cable at the car bottom (e.g., ...). Figure 1 (Center line C) to prevent interference and random swinging between the traveling cables 105 during elevator operation, which could cause damage.
[0045] This utility model achieves its effect by breaking... Figure 1The connection between C (traveling cable 105 center) and D (car rail 113 center) is directly installed on the inner wall of the hoistway, regardless of the guide rail or elevator type. This single-model cable bracket is universal, reducing size, saving materials, and lowering production costs. It can be used with different elevator models, facilitating mass production and reducing the risk of incorrect or missing installations.
[0046] Furthermore, in some preferred embodiments, a number of removable pads 107 are provided between the support base plate 101 and the first clamping plate 103, so that the distance between the first clamping plate 103 and the support base plate 101 is adjustable.
[0047] In this utility model, by setting several detachable pads 107, the distance between the formed clamping area 114 and the inner wall 102 of the shaft can be adjusted, ensuring that the distance between the traveling cable 105 and the inner wall 102 of the shaft can be adjusted, and avoiding interference between the traveling cable 105 and the inner wall 102 of the shaft.
[0048] Furthermore, in some preferred embodiments, longitudinal slide rails are symmetrically arranged on both sides of the support base plate 101, the pad 107 is slidably arranged on the longitudinal slide rails, and a terminal locking device is provided at the end of the longitudinal slide rails to fix the pad 107 and the first clamping plate 103.
[0049] This utility model uses a detachable pad 107 to adjust the distance between the bracket base plate 101 and the first clamping plate 103, and uses the pads 107 stacked to change the height of the clamping area 114.
[0050] Furthermore, the pad 107 and the longitudinal slide rail are slidably connected via a groove. The slide rail serves to guide and limit movement, improving ease of installation.
[0051] In some preferred embodiments, the longitudinal slide rail can be a guide rod 108, which is threaded and has a nut 109 at its end to fix the first clamping plate 103 to several removable pads 107.
[0052] Furthermore, the groove is a T-shaped or dovetail-shaped groove.
[0053] The pad 107 includes at least one base pad 110 and expandable additional pads 107.
[0054] The base pad is 110, with a thickness of 8-12mm; specifically, it can be 8mm, 9mm, 10mm, 11mm, 12mm, etc.
[0055] Additional pad 107, with a thickness of 1-7mm, specifically 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, etc.; both the base pad 110 and the additional pad 107 slide in conjunction with the longitudinal slide rail.
[0056] This utility model uses a combination of a base pad 110 and an additional pad 107 to achieve high subdivision through combination mathematics.
[0057] Furthermore, in this invention, the pad material can be hard rubber, which reduces the cost of the pad.
[0058] The first clamping plate 103 is provided with a guide groove corresponding to the longitudinal slide rail, and the side of the first clamping plate 103 is provided with a threaded hole. The terminal locking device is a locking screw that mates with the threaded hole. The locking screw is used to fix the first clamping plate 103.
[0059] Furthermore, the first clamping plate 103 and the second clamping plate 104 are made of plastic, and the first clamping plate 103 and the second clamping plate 104 are connected by screws.
[0060] Among them, the first clamping plate 103 and the second clamping plate 104 are provided with anti-slip texture on the side that contacts the traveling cable 105. The anti-slip texture is an anti-slip raised texture, which improves the fixing effect on the traveling cable 105.
[0061] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
