Description

Technical Field

[0001] This utility model relates to the field of weighing, specifically a weighing sensor mounting base. Background Technology

[0002] Dynamic weighing technology (WIM Weight In Motion) refers to the devices and methods used to measure the weight of moving objects. It is widely used in many fields such as rail transit, highway off-site enforcement, source control of overloading, logistics sorting, and sorting scales. The market demand for products based on dynamic weighing technology is huge. On railways, equipment used to weigh the loaded goods on passing trains is called a track scale. The principle of track scale measurement is based on the weight of the vehicle and load acting on a sensor through a platform. The sensor deforms, and a voltage signal is output through a bridge circuit. Computers and electronic instruments identify, analyze, and calculate this voltage signal to obtain the final weight value. However, in large-scale use and testing, sensors need to be installed to achieve the weighing purpose. The installation of the sensors themselves is relatively limited, as they cannot be securely installed on the track surface, etc. Summary of the Invention

[0003] The purpose of this invention is to provide a weighing sensor mounting base to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a weighing sensor mounting base, including a base, with a support plate connected to the upper end of the base via several stabilizers. Two sensors symmetrically arranged front and rear can be fixedly mounted on the support plate. The sensors can detect pressure data and thus obtain the weighing result. The stabilizers can buffer when the weight is too high, preventing damage to the sensors.

[0005] The stabilizer includes a sliding sleeve fixedly connected to the upper end face of the base, a sliding cavity with an upper opening inside the sliding sleeve, a magnetic slide plate slidably connected to the sliding cavity, a buffer spring connected between the lower end face of the magnetic slide plate and the lower end wall of the sliding cavity, an electromagnet fixedly installed at the lower end of the sliding cavity, and the electromagnet can provide support force to the magnetic slide plate when activated, and a support column fixedly connected to the lower end face of the support plate is fixedly connected to the upper end face of the magnetic slide plate.

[0006] The sensor is fixedly connected to a fixing plate at its upper end. The fixing plate has several guide holes running through it from top to bottom. A protective plate is provided on the upper side of the fixing plate. The protective plate has a sleeve cavity with a lower opening inside, and the sleeve cavity can fit the fixing plate.

[0007] The lower end face of the sleeve is fixedly connected with a number of guide posts corresponding one-to-one with the guide holes. The upper end of the protective plate is used to support the object to be weighed, and it is convenient to replace the protective plate after it is damaged by long-term use.

[0008] A mounting block is fixedly connected to each of the left and right end faces of the base. The mounting block has several through mounting holes for mounting and fixing the mounting block.

[0009] The front end face of the mounting block is fixedly connected to a connecting block, and the connecting block is threadedly connected to a connecting stud.

[0010] An auxiliary block is fixedly connected to the rear end face of the mounting block. The auxiliary block has a connecting hole extending through its upper and lower ends. The auxiliary block can overlap with the connecting block connected to another mounting block. At this time, the connecting stud of the other connecting block can be spirally inserted into the connecting hole to fix it in place.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model, through the installation block, allows the base and the installation block to be installed and fixed through the installation holes provided on the installation block, which is convenient for installation and fixing on the track or road surface. Furthermore, the connecting block and connecting holes fixedly connected by the installation block can realize the mutual fixed connection of multiple bases, which is convenient for the simultaneous use of multiple of this utility model.

[0013] The protective plate protects the sensor from damage caused by direct contact with the object being weighed. Since the protective plate is slidably connected to the fixed plate that is fixed to the sensor, it is easy to replace the protective plate that is damaged after a period of use. The stabilizer can move the sensor downwards when the weight exceeds the limit of the magnetic slide plate to prevent damage. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please see Figure 1-5 This utility model provides a technical solution: a weighing sensor mounting base, including a base 101. The upper end of the base 101 is connected to a support plate 111 through a plurality of stabilizers 109. Two sensors 112 symmetrically arranged front and back can be fixed on the support plate 111. The sensors 112 can detect pressure data and thus obtain the weighing result. The stabilizers 109 can buffer when the weight is too high to prevent the sensors 112 from being damaged.

[0023] The stabilizer 109 includes a sliding sleeve 118 fixedly connected to the upper end face of the base 101. The sliding sleeve 118 has a sliding cavity 119 with an upper opening. A magnetic slide plate 122 is slidably connected to the sliding cavity 119. A buffer spring 123 is connected between the lower end face of the magnetic slide plate 122 and the lower end wall of the sliding cavity 119. An electromagnet 121 is fixedly installed at the lower end of the sliding cavity 119. When the electromagnet 121 is activated, it can provide support force to the magnetic slide plate 122. A support column 124 fixedly connected to the upper end face of the magnetic slide plate 122 and fixedly connected to the lower end face of the support plate 111 is fixedly connected.

[0024] The upper end of the sensor 112 is fixedly connected to a fixing plate 113. The fixing plate 113 has several guide holes 114 running through it vertically. A protective plate 115 is provided on the upper side of the fixing plate 113. The protective plate 115 has a sleeve cavity 116 with a lower opening inside. The sleeve cavity 116 can fit into the fixing plate 113.

[0025] The lower end face of the sleeve 116 is fixedly connected with a plurality of guide posts 117 corresponding one-to-one with the guide holes 114. The upper end of the protective plate 115 is used to support the object to be weighed. After the protective plate 115 is damaged by long-term use, it is easy to replace.

[0026] A mounting block 102 is fixedly connected to the left and right end faces of the base 101, and the mounting block 102 is provided with a plurality of vertically penetrating mounting holes 103, which are used to install and fix the mounting block 102.

[0027] The front end face of the mounting block 102 is fixedly connected to the connecting block 104, and the connecting block 104 is threadedly connected to the connecting stud 105.

[0028] An auxiliary block 107 is fixedly connected to the rear end face of the mounting block 102. The auxiliary block 107 has a connecting hole 106 extending through its upper and lower ends. The auxiliary block 107 can overlap with the connecting block 104 connected to another mounting block 102. At this time, the connecting stud 105 of the other connecting block 104 can spirally enter the connecting hole 106 and thus fix it.

[0029] Working principle:

[0030] In use, the base 101 is installed and fixed through the mounting holes 103 on the two mounting blocks 102, thereby fixing the stabilizer 109, support plate 111, sensor 112 and fixing plate 113. Then, the cavity 116 of the protective plate 115 is slid into the fixing plate 113, and the positioning and fixing are completed by the guide post 117, thus completing the installation. At this time, the electromagnet 121 is activated to push the magnetic slide plate 122 to keep the support post 124 from moving downward.

[0031] At this time, the pressure is applied to the upper side of the protective plate 115, the fixed plate 113 and the sensor 112 by the pressure. The sensor 112 can detect the pressure and thus obtain the weighing result.

[0032] During the weighing process, if the pressure detected by sensor 112 reaches the set threshold, and continuing the measurement may damage sensor 112, electromagnet 121 is turned off and no longer supports support column 124. At this time, support plate 111, sensor 112, fixed plate 113 and protection plate 115 move downward and stop weighing the object to avoid damage to sensor 112.

[0033] If multiple sensors 112 need to be used together, the connecting block 104 of another base 101 is locked onto the connecting hole 106 of the first base 101, and the connecting stud 105 is rotated to fix the two bases 101 together so that they can be used together.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
