Description
Technical Field
[0001] This invention relates to the field of gravity sensor installation technology, specifically to a gravity sensor installation structure for a track scale. Background Technology
[0002] A rail scale is a weighing instrument used to measure the weight of freight cars on railways. There are three types: static rail scales, dynamic rail scales, and light rail scales. They are widely used in factories, mines, metallurgy, foreign trade, and railway sectors for weighing bulk cargo in freight cars.
[0003] When installing rail scales, the whole installation method is often adopted. During the foundation construction, sleepers are needed to support the rail scale. Since the foundation construction is carried out in the passage under the coal bunker, the height needs to be adjusted according to the ring shape of the site. Moreover, because the coal bunker space is narrow, the working space of the construction personnel is already very small. The sleepers occupy space, which further reduces the working space of the construction personnel. Therefore, the foundation construction of rail scales is difficult. Summary of the Invention
[0004] Therefore, the purpose of this invention is to provide a gravity sensor mounting structure for a track scale to solve the technical problems mentioned in the background above.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a gravity sensor mounting structure for a track scale, comprising a base, a top plate above the base, two sets of second reinforcing plates in contact with the base at the bottom of the top plate, a first reinforcing plate in contact with the top plate at the outer side of the second reinforcing plates at the top of the base, two sets of heightening components at the inner side of the second reinforcing plates at the top of the base, and two pairs of weighing components installed on the outer side of the heightening components at the top of the base;
[0006] The height-increasing component includes two sets of fixed ladder plates fixed to the top of the base, and two sets of movable ladder plates movably connected to the bottom of the top plate between the two sets of fixed ladder plates. Two sets of driven blocks are fixed on the inner side of the two sets of movable ladder plates, and positive and negative lead screws are sleeved on the inner wall of the two sets of driven blocks.
[0007] The weighing assembly includes a base fixed to the top of a base, a limiting component movably connected to the top of the base, a connecting core extending to the top of the limiting component being sleeved on the inner wall of the limiting component, a lifting cylinder being sleeved on the outer wall of the top of the connecting core, and a gravity sensor being installed at the top of the lifting cylinder.
[0008] By adopting the above technical solution, rotating the positive and negative screws causes the two sets of movable base plates to move away from each other and to the required position, lowering the top plate and engaging the movable ladder plate with the fixed ladder plate, thus adjusting the height of the top plate to suit different working environments and expanding the application range of the device.
[0009] The invention is further configured such that weighing bars are provided on both sides of the top end of the top plate, and the weighing bars are fixed to the track by a screw.
[0010] By adopting the above technical solution, an installation base point is provided for the track, which can be fixed to the track to carry out the weighing work.
[0011] The present invention is further configured such that connecting arms fixed to the bottom end of the top plate are sleeved at both ends of the positive and negative lead screws, and the two ends of the positive and negative lead screws are rotatably connected to the connecting arms through bearings.
[0012] By adopting the above technical solution
[0013] The invention is further configured such that the top of the movable ladder plate is provided with a dovetail block extending into the bottom of the top plate, and the bottom of the top plate is provided with a matching dovetail groove.
[0014] By adopting the above technical solution, the movable ladder plate is guided and limited, allowing it to move linearly along the bottom of the top plate.
[0015] The present invention is further configured such that a matching positive thread is formed at the contact position between the outer wall of the positive and negative lead screw and the inner wall of a set of driven blocks, and a matching negative thread is formed at the contact position between the outer wall of the positive and negative lead screw and the inner wall of another set of driven blocks.
[0016] By adopting the above technical solution, a force is provided to the two sets of driven blocks to move in opposite directions, thereby controlling the two sets of driven blocks to move in opposite directions.
[0017] The present invention is further configured such that the top end of the connecting core is provided with a spring that is fixed to the top end of the inner wall of the lifting cylinder.
[0018] By adopting the above technical solution, the lifting cylinder is lowered by a certain stroke, thus providing shock absorption protection for the gravity sensor.
[0019] The present invention is further configured such that the outer wall of the connecting core is provided with two sets of limiting plates extending into the interior of the limiting component, the limiting component includes a limiting cylinder, the inner wall of the limiting cylinder is provided with a guide groove larger than the size of the limiting plate, and a plurality of limiting seats are fixed on one side of the inner wall of the guide groove.
[0020] By adopting the above technical solution
[0021] In summary, the present invention has the following main beneficial effects:
[0022] 1. This invention uses a top plate, a height-increasing component, a fixed ladder plate, a movable ladder plate, positive and negative lead screws, and a driven block to work together. By rotating the positive and negative lead screws, the two sets of movable base plates move away from each other and move to the required position. The top plate is then lowered, causing the movable ladder plate to engage with the fixed ladder plate, thus adjusting the height of the top plate. This allows it to be used in different working environments and expands the application range of the device.
[0023] 2. This invention uses a weighing component, a gravity sensor, a lifting cylinder, a base, a connecting core, a limiting component, a spring, and a limiting plate to work together to adjust the height of the gravity sensor. This, in conjunction with the top plate, enables the weighing of tracks at different heights. At the same time, the spring buffers the force when the top plate is lowered, preventing damage from direct impacts. This design offers high flexibility while increasing service life.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0034] The embodiments of the present invention will now be described.
[0035] A gravity sensor mounting structure for a track scale, such as Figure 1-8 As shown, it includes a base 1, a top plate 2 above the base 1, two sets of second reinforcing plates 4 at the bottom of the top plate 2 that are in contact with the base 1, a first reinforcing plate 3 at the top of the base 1 outside the second reinforcing plate 4 that is in contact with the top plate 2, two sets of heightening components 5 at the top of the base 1 inside the second reinforcing plate 4, and two pairs of weighing components 6 installed on the outside of the heightening components 5 at the top of the base 1.
[0036] The heightening component 5 includes two sets of fixed ladder plates 51 fixed to the top of the base 1, and two sets of movable ladder plates 52 movably connected to the bottom of the top plate 2 between the two sets of fixed ladder plates 51. The top of the movable ladder plate 52 is provided with a dovetail block extending into the bottom of the top plate 2, and the bottom of the top plate 2 is provided with a matching dovetail groove. Two sets of driven blocks 54 are fixed to the inner side of the two sets of movable ladder plates 52, and positive and negative screw rods 53 are sleeved on the inner wall of the two sets of driven blocks 54.
[0037] The weighing component 6 includes a base 63 fixed to the top of the base 1. A limiting component 65 is movably connected to the top of the base 63. A connecting core 64 extending to the top of the limiting component 65 is sleeved on the inner wall of the limiting component 65. A spring 66 fixed to the top of the inner wall of the lifting cylinder 62 is provided at the top of the connecting core 64. The lifting cylinder 62 is sleeved on the outer wall of the top of the connecting core 64. A gravity sensor 61 is installed at the top of the lifting cylinder 62.
[0038] Please see Figure 1 Weighing bars are provided on both sides of the top of the top plate 2. The weighing bars are fixed to the track by screws, providing support points for the track. Once fixed to the track, the weighing process can be carried out.
[0039] Please see Figure 2 and Figure 3 The two ends of the positive and negative lead screw 53 are fitted with connecting arms 55 that are fixed to the bottom end of the top plate 2. The two ends of the positive and negative lead screw 53 are rotatably connected to the connecting arms 55 through bearings, which reduces the friction between the ends of the positive and negative lead screw 53 and the connecting arms 55, making it smooth and labor-saving when rotated manually.
[0040] Please see Figure 2 and Figure 3 The outer wall of the positive and negative lead screw 53 is provided with a matching positive thread at the contact position with the inner wall of a set of driven blocks 54, and the outer wall of the positive and negative lead screw 53 is provided with a matching negative thread at the contact position with the inner wall of another set of driven blocks 54. When the positive and negative lead screw 53 is rotated, the positive and negative threads on the outer wall cause the two sets of driven blocks 54 to move away from each other, dragging the two sets of movable ladder plates 52 at the end to move accordingly, so that the height of the top plate 2 can be adjusted.
[0041] Please see Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The outer wall of the connecting core 64 is provided with two sets of limiting plates 67 extending into the interior of the limiting component 65. The limiting component 65 includes a limiting cylinder 651. The inner wall of the limiting cylinder 651 is provided with a guide groove 652 larger than the size of the limiting plate 67. Multiple sets of limiting seats 653 are fixed on one side of the inner wall of the guide groove 652, so that the limiting plate 67 and the limiting seat 653 are not in the same vertical plane, which can raise the connecting core 64 to the required height. Reversing the direction will reset it. Through the cooperation of the limiting seat 653 and the limiting plate 67, the connecting core 64 is supported and fixed at the required height.
[0042] The working principle of this invention is as follows: During installation, the top plate 2 is lifted to a suitable height by an external lifting device. A person holds the lifting cylinder 62 with one hand and rotates the limiting component 65 around the contact point with the base 63 with the other hand, so that the limiting seat 653 and the limiting piece 67 are misaligned and not on the same vertical plane. The lifting cylinder 62 is lifted, which drives the connecting core 64 to rise along the inner wall of the limiting component 65. At the same time, the limiting piece 67 slides and rises to the required height on the inner wall of the guide groove 652. Then, the limiting component 65 is reversed, which drives the limiting piece 67 on the outer wall of the connecting core 64 to the top of the limiting seat 653, supporting the raised connecting core 64 and fixing it at the required height. The spring 66 buffers the force when the top plate 2 is lowered, avoiding damage to the gravity sensor 61.
[0043] Next, rotate the positive and negative screws 53, and through the positive and negative threads on the outer wall, move the two sets of driven blocks 54 away from each other, and drive the two sets of movable ladder plates 52 at the end to move away from each other. The lifting device gradually lowers the top plate 2 until it engages with the fixed ladder plate 51, supporting the adjusted top plate 2 and preventing deformation caused by uneven force on the top plate 2. This indirectly protects the top plate 2. Connect the external track to the top of the top plate 2, and the weighing work can be carried out.
