Description

TECHNICAL FIELD

[0001] The utility model relates to sensor installation technical field, concretely relates to a kind of installation system of separation for axle counting sensor installation. BACKGROUND

[0002] With the consciousness of environmental protection in modern society is enhanced, straddle-type light rail train is gradually become one of the traffic modes for improving traffic pressure in recent urban development planning because of high operation, low investment, short cycle, especially the characteristics of zero pollution. As the safety inspection equipment for judging track vacancy and occupation, microcomputer axle counting equipment provides strong guarantee for the safe, reliable and stable operation of straddle-type light rail train.

[0003] The track of modern straddle-type light rail train usually adopts the mode of cement bridge. In order to enable the axle counting sensor to successfully detect the stable wheel located at the side of straddle-type light rail train, it is necessary to install the axle counting transmitter and receiver at the upper and lower ends of the negative side of the bridge respectively, and the center of the two sensors is the center of the stable wheel of straddle-type light rail train when traveling. There are two kinds of traditional installation modes:

[0004] 1. The sensor is installed by hole drilling mode through electric hammer at the upper and lower ends of the negative side of the cement beam. Usually, the cement beam is installed on the viaduct pier on site. Since the deviation of the four holes (diameter 15mm) drilled by electric hammer at the upper and lower ends of the hard cement beam in horizontal direction and vertical direction is large, the accuracy cannot be guaranteed, which leads to the fact that the transmitter and receiver installed at the upper and lower ends are not concentric in vertical direction, and are inclined left and right in horizontal direction, so that the axle counting sensor cannot reliably detect the stable wheel of the train, the failure rate is high, the stable operation of the axle counting equipment is affected, and the reliability is reduced. At the same time, it is difficult to drill holes in high altitude on site, and the hole drilling by electric hammer affects the quality of the bridge, so this mode is not accepted by users.

[0005] 2. The sensor is installed by the mode of pre-embedded integral mounting bracket before the early stage of cement beam production. Since the specific position of sensor installation cannot be determined during the production process of cement beam, it cannot be accurately controlled during pre-embedding, and during the process of cement beam pouring and vibrating, the pre-embedded bracket is prone to displacement and inclination and distortion. Since this pre-embedded integral mounting bracket mode does not belong to the standard pre-embedding mode of urban rail transit, it brings great difficulty to the production of cement bridge factory, seriously affects the production efficiency of cement bridge, and the installation point of axle counting sensor must be checked when the bridge is erected on site, which greatly affects the construction.

[0006] Since the height of the stable wheel of different light rail train models is inconsistent, the equipment limit height requirement of the train is also different. The above two modes need to be constructed according to the actual train model of each line, and the operation difficulty is relatively large. Practical new type content

[0012] Further, locking pad is also matched and arranged on threaded column body, and locking pad is attached to the upper surface of support seat in locking state.

[0013] Further, second mounting bracket includes second base plate and mounting seat being obliquely arranged on second base plate, and receiver is installed on mounting seat, and locking hole matched with T-shaped locking piece is opened on second base plate.

[0014] Further, T-shaped locking piece adopts T-shaped bolt and nut matched with T-shaped bolt.

DETAILED DESCRIPTION

[0024] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used for explaining the utility model and are not used for limiting the scope of the utility model.

[0025] like Figures 1 to 5 As shown, a separate mounting system for mounting an axle counter sensor includes a channel 1 cut into a bridge, a first mounting bracket 3 for mounting a transmitter 2, a second mounting bracket 5 for mounting a receiver 4, and a T-shaped locking member 6 for mates the first mounting bracket 3 and the second mounting bracket 5 within the channel 1. The axle counter sensor includes a transmitter and a receiver 4. In this application, mounting brackets are provided for mounting the transmitter and receiver 4 respectively. The first mounting bracket 3 is connected to the channel 1 via the T-shaped locking member 6, ensuring that the transmitter 2 can be stably fixed to the bridge, while maintaining the relative position of the transmitter 2 and the receiver 4 for accurate signal transmission. The second mounting bracket 5 is similar to the first mounting bracket 3, also connected to the channel 1 via the T-shaped locking member 6, ensuring that the receiver 4 can be stably fixed to the bridge and receive signals transmitted by the transmitter 2. The T-shaped locking member 6 is a key component connecting the channel 1 and the mounting bracket. The teeth 61 on its flat end 60 engage with the teeth 61 within the channel 1, ensuring that the locking member is securely fixed within the channel 1. Meanwhile, the cylindrical end 62 of the T-shaped locking member 6 is connected with the first mounting bracket 3 and the second mounting bracket 5 to achieve stable fixation of the mounting bracket.

[0026] During installation, first install the transmitter 2 onto the first mounting bracket 3 and the receiver 4 onto the second mounting bracket 5. Then, screw the T-shaped locking piece 6 into the sensor channel 1 pre-embedded on the negative side of the cement bridge. Fix the assembled transmitter 2 mounting bracket, receiver 4, and mounting bracket onto the T-bolt. Adjust the installation height of the sensor by using the teeth 61 that mate with the T-bolt and the channel 1. Once adjusted, tighten the T-shaped locking piece 6.

[0027] The flat end 60 of the T-shaped locking member 6 and the groove 1 are respectively provided with teeth 61, and the teeth 61 on the flat end 60 of the T-shaped locking member 6 and the teeth 61 in the groove 1 are engaged. The cylindrical end 62 of the T-shaped locking member 6 is connected to the first mounting bracket 3 and the second mounting bracket 5. Through the engagement of the teeth 61 in the groove 1, the installation height of the sensor can be easily adjusted by simply moving the T-shaped locking member 6, which is convenient. At the same time, the engagement design of the teeth 61 makes the position of the mounting bracket relatively stable and not easy to loosen due to vibration when the train passes. In addition, this design also increases the connection strength between the mounting bracket and the bridge structure, ensuring the stability and reliability of the axle counting sensor. In order to save costs, the T-shaped locking member 6 preferably uses a T-bolt and a nut that mates with the T-bolt. The spacing of the teeth 61 in the groove 1 is only 3mm, so fine adjustment of the height of the installed equipment can be achieved, ensuring that the installation size requirements of the equipment are optimal, and providing a guarantee for the stable and reliable operation of the detection equipment.

[0028] like Figure 6 As shown, the first mounting bracket 3 includes a first base plate 30, mounting ramps 31 inclined at both ends of the first base plate 30, an arc-shaped block 32 disposed on the mounting ramps 31, and a locking post 33 disposed on the mounting ramps 31. The upper surface of the arc-shaped block 32 is provided with upper teeth 34, and the lower surface of the support base 20 of the transmitter 2 is provided with lower teeth 35 that cooperate with the upper teeth 34. The support base 20 is locked onto the arc-shaped block 32 by the locking post 33. The first base plate 30 is provided with locking holes 36 that cooperate with the T-shaped locking member 6. The first base plate 30 serves as the base of the first mounting bracket 3, providing a stable support surface for mounting and fixing other components. The locking holes 36 on it are used to cooperate with the T-shaped locking member 6 to fix the first mounting bracket 3 at the opening of the bridge channel 1. The mounting ramps 31 provide a certain tilt angle to adapt to the shape of the support base 20 of the transmitter 2 and the installation requirements. The upper surface of the arc-shaped block 32 is provided with upper teeth 34, which are used to cooperate with the lower teeth 35 on the lower surface of the transmitter 2 support 20. This toothed engagement design ensures that the transmitter 2 can be stably fixed on the arc-shaped block 32, making it less likely to fall off due to vibration or impact. On the other hand, the installation position between the support 20 and the arc-shaped block 32 can be adjusted according to the installation angle requirements of the transmitter 2, thereby adjusting the installation angle of the transmitter 2, making the operation convenient and reliable.

[0029] The locking post 33 includes a threaded post 330 and a locking nut 331 threaded onto the threaded post 330. The threaded post 330 passes through both the arc-shaped block 32 and the support seat 20 of the transmitter 2, and is locked in place by the locking nut 331. A locking washer 37 is also provided on the threaded post 330. In the locked state, the locking washer 37 is in contact with the upper surface of the support seat 20. The locking nut 331 is threaded onto the threaded post 330 to lock the support seat 20 onto the arc-shaped block 32. By rotating the locking nut 331, it can be moved along the threaded post 330, thereby achieving the fastening effect on the support seat 20. The locking washer 37 is provided on the threaded column 330. When the locking nut 331 is tightened, the locking washer 37 will fit against the upper surface of the support 20. The design of the locking washer 37 increases the locking friction and stability, prevents the support 20 from loosening under vibration or impact, and avoids damage to the support 20.

[0030] like Figure 7As shown, the second mounting bracket 5 comprises a second base plate 50 and a mounting seat 51 obliquely arranged on the second base plate 50, the receiver 4 is mounted on the mounting seat 51, and locking holes 36 cooperating with the T-shaped locking pieces 6 are arranged on the second base plate 50. By fixing the second base plate of the second mounting bracket at the groove opening of the bridge and locking by the T-shaped locking pieces, the stability and reliability of the second mounting bracket are ensured, and the design of the mounting seat enables the receiver to be stably mounted thereon and not easily fall off due to vibration or impact.

[0031] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
