Description

Technical Field

[0001] This utility model mainly relates to the field of material storage, specifically a track-type material inventory device. Background Technology

[0002] At present, most project companies still rely on manual inventory counting to check the inventory of materials. However, manual inventory counting has disadvantages such as limited methods and narrow scope, which often leads to a large error between the manual inventory count and the actual inventory. Moreover, manual inventory counting is time-consuming, labor-intensive, and wastes human and material resources.

[0003] To address this issue, Chinese utility model CN218601465U discloses an intelligent inventory device for storage silos, mainly used for inventorying sand and gravel materials in the daily production of mixing plants. This device is also installed on a track and can operate intelligently. However, the device itself has a relatively simple structure and is prone to unstable operation.

[0004] Therefore, a track-mounted material inventory device is needed that can travel on tracks under different conditions, thereby increasing its stability. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model provides a fan pressure line measuring device.

[0006] The technical solution of this utility model is as follows: A track-type material inventory device is installed under a track, including a base, a moving structure, a tensioning structure, and supports arranged on the left and right sides of the track. The base is slidably connected to the track via a bracket; The moving structure includes a motor, a transmission mechanism, and a friction wheel. The motor is mounted on the base and connected to the friction wheel through the transmission mechanism. The friction wheel is in close contact with the track and can move along the length of the track. The tensioning structure includes a fixed plate and a first spring arranged on both sides of the track. One end of the fixed plate is rotatably connected to the friction wheel, and the other end is rotatably mounted on the base. The first spring is connected between the fixed plate and the bracket in a tensioned state. A radar is installed at the bottom of the base.

[0007] In the device, the tension of the first spring continuously acts on the fixed plate. Since one end of the fixed plate is rotatably connected to the base, and the other end is always raised due to the tension, the friction wheel located on the fixed plate can remain firmly against the underside of the track, ensuring the device's movement even with complex track conditions. When the motor starts, its output drives the friction wheel to roll via a transmission mechanism, using friction to propel the device along the track. After the device stops on the track, the radar can be remotely controlled or automatically activated to scan for materials.

[0008] In this embodiment, a radar rotation mechanism is installed below the base, and a measuring radar is installed below the rotation mechanism. The radar can rotate 180°.

[0009] A central shaft runs through both ends of the friction wheel, with the shaft fixedly connected to it. Bearing seats are located at both ends of the central shaft, which is connected to bearings within these seats. This reduces friction and wear during rotation, ensuring smooth rotation of the friction wheel. The bearing seats are located on the inner upper side of the fixed plate, also serving to secure the central shaft.

[0010] Furthermore, the friction wheel is keyed to the central shaft, ensuring connection strength, guaranteeing the stability of mechanical transmission, and facilitating machining and installation.

[0011] In this invention, the transmission mechanism includes a main pulley, a driven pulley, and a belt. The belt drive structure is simple and inexpensive. The main pulley is located on the output shaft of the motor, and the driven pulley is located at one end of the central shaft on the same side as the motor, between the friction wheel and the bearing seat. The belt is fitted onto the main pulley and the driven pulley and is arranged parallel to the fixed plate.

[0012] The support system comprises two lower supports, two upper supports, and two horizontal supports. These supports, distributed along both sides of the track, ensure stable movement of the equipment, preventing swaying or deformation. The two lower supports are located at the front and rear ends of the base, respectively, with the upper supports fixedly connected to them and extending to the track. The two horizontal supports are U-shaped protrusions, with their ends fixedly connected to the two upper supports. A first pulley is installed at the top of each upper support, positioned at the upper edge of the track. Second pulleys are located inside the horizontal supports, situated on the sides of the track. These multiple pulleys reduce friction during device movement.

[0013] The upper support is a U-shaped support, which provides space for the track when supporting the suspension device. The lower support is an inverted U-shaped support, with the bottom of the upper support and the top of the lower support fixedly connected, and both are arranged in the left-right direction. The upper end of the upper support is located on both sides of the track, and the first pulley is vertically installed on its inner side. The first pulley slides on the edge of the upper surface of the track, and works together with the tensioning structure to form a clamping tendency, so that the device can travel stably under the track.

[0014] The horizontal supports are located on both sides below the track, with their middle section situated outside the fixed plate to prevent friction and collision between components. Furthermore, the length of this middle section matches the spacing of the upper supports and is parallel to the track side. The horizontal supports connect to the upper supports, increasing the overall strength of the support system.

[0015] In this embodiment, a "7"-shaped first connecting plate is movably connected to both ends of the inner side of the middle section of the horizontal support via horizontal bolts. A horizontally arranged second pulley is connected to the top of the first connecting plate. A second spring is sleeved on the horizontal bolts. The second spring can continuously compress the first connecting plate, causing the second pulley to abut against the side of the track. Because the second spring can continuously push the first connecting plate, the second pulley can always provide pressure to the side of the track, increasing the horizontal stability of the device.

[0016] Furthermore, two second pulleys are provided on each side of the track to clamp the track in the horizontal direction, ensuring that the device will not shift left or right.

[0017] The fixing plate is a plate-shaped structure set at an angle, parallel to the side of the track. The first spring is located between the fixing plate and the horizontal support, and the upper and lower ends are respectively connected to the fixing plate and the middle position of the horizontal support through the second connecting plate.

[0018] As an improvement of this utility model, the second connecting plate can be an "L" shaped structure, with one part being wider and able to be fixedly connected to the fixed plate or horizontal bracket by two bolts, and the other part being narrower, extending outward or inward and being penetrated by bolts. The bolt tail can have an opening. The first spring can be a hook spring with hooks at both ends, which is fixed by passing the hooks through the openings.

[0019] As another improvement of this utility model, the first spring is located between the two second pulleys, and the specific position can be confirmed during use.

[0020] In this invention, a position sensor is installed on the track, a sliding contact line is installed above the track, and a current collector is installed at the upper end of the upper support. The two are in contact and provide power to the device through a wire.

[0021] Furthermore, the current collector can be installed on the outer side of the upper end of the upper bracket, extending upward to contact the sliding contact line.

[0022] In this device, the U-shaped bracket design saves space and reduces weight. Under the tension of the first spring, the friction wheel can always use friction to propel the device. Simultaneously, due to the movable connection of the fixed plate, the friction wheel can move within a certain range, making it suitable for tracks that are not perfectly straight. The first pulley not only reduces the friction force propelling the device forward but also works in conjunction with the friction wheel to vertically clamp the track, enabling the device to travel stably on the track.

[0023] The second pulley in the device constantly applies pressure to the side of the track to prevent the device from shifting during operation. Because the first connecting plate is movable, the second pulley can move inward and outward within a certain range. Even if the track width changes slightly due to deformation or other reasons, the second pulley can still prevent the device from swaying left and right. Attached Figure Description

Support; 101. Lower support; 102. Upper support; 103. Horizontal support; 2. Base; 3. Moving structure; 301. Motor; 302. Transmission mechanism; 303. Friction wheel; 4. Tensioning structure; 401. Fixing plate; 402. First spring; Detailed Implementation See Figures 1-6 As shown, this embodiment provides a track-type material inventory device, which is installed under the track and includes a base 2, a moving structure 3, a tensioning structure 4, and brackets 1 set on the left and right sides of the track. Base 2 is slidably connected to the bottom of the track via bracket 1; The moving structure 3 includes a motor 301, a transmission mechanism 302 and a friction wheel 303. The motor 301 is mounted on the base 2 and is connected to the friction wheel 303 through the transmission mechanism 302. The friction wheel 303 is in close contact with the track and can move along the length of the track. The tensioning structure 4 includes a fixed plate 401 and a first spring 402 arranged on both sides of the track. One end of the fixed plate 401 is rotatably connected to the friction wheel 303, and the other end is rotatably arranged on the base 2. The first spring 402 is connected between the fixed plate 401 and the bracket 1 in a tensioned state. A radar is installed below base 2.

[0025] In the device, the tension of the first spring 402 continuously acts on the fixed plate 401. Since one end of the fixed plate 401 is rotatably connected to the base 2, and the other end is always raised due to the tension, the friction wheel 303 located on the fixed plate 401 can remain firmly against the bottom of the track, ensuring the device's movement even when the track conditions are complex. When the motor 301 starts, its output end drives the friction wheel 303 to roll via the transmission mechanism 302, using friction to propel the device along the track. After the device stops on the track, the radar can be remotely controlled or automatically activated to scan materials.

[0026] Let's take a look at the specific design of each component: See Figure 3 and Figure 4 Regarding the design of bracket 2, bracket 2 includes two lower brackets 101, two upper brackets 102 and two horizontal brackets 103, which are symmetrically arranged on the left and right sides of the track.

[0027] Preferably, the lower support 101 is an inverted "U"-shaped support, with two lower supports 101 respectively located at the front and rear ends of the base 2. The upper support 102 is a "U"-shaped support, fixedly connected to the lower support 101, with the other end extending upwards. The upper end of the upper support 102 is vertically located on both sides of the track, with a first pulley vertically installed on its inner side, sliding on the edge of the track's upper surface. The two horizontal supports 103 are outwardly protruding "V"-shaped supports, with their two ends fixedly connected to the two upper supports 102.

[0028] The horizontal bracket 103 is located on both sides below the track, and its left and right ends can be fixed to the outside of the upper bracket with two horizontal bolts. Its middle section is located outside the fixing plate 401, not exceeding the edge of the base 2, and the length of the middle section matches the interval of the upper bracket 102 and is parallel to the side of the track. A second pulley is provided inside the horizontal bracket 103, located on the side of the track.

[0029] See Figure 7 In this embodiment, a "7"-shaped first connecting plate is movably connected to both ends of the inner side of the middle section of the horizontal support 103 via horizontal bolts. A horizontally arranged second pulley is connected to the top of the first connecting plate, and a second spring is sleeved on the horizontal bolt. The second spring is located between the first connecting plate and the horizontal support, and can continuously compress the first connecting plate, causing the second pulley to abut against the side of the track.

[0030] Furthermore, the vertical end of the first connecting plate is wider than the horizontal end. Its horizontal end has rounded corners, and its edge does not contact the side of the slide rail. Two second pulleys are respectively provided on both sides below the track. Each first connecting plate can be movably connected to two horizontal bolts, ensuring that the second pulleys can be fixed horizontally while allowing the first connecting plate to slide along the bolts within a certain range.

[0031] See Figure 2 and Figure 5 A central shaft is installed at the center of the friction wheel 303, extending through both ends. The central shaft is fixedly connected to the friction wheel, and bearing seats are installed at both ends of the central shaft. The central shaft is connected to the bearings in the bearing seats. The bearing seats are located on the inner side of the upper end of the fixed plate 401 and can be connected by bolts.

[0032] Furthermore, the friction wheel 303 can be made of wear-resistant material with a certain strength. If there is a certain requirement for the working volume, rubber material can be considered. The friction wheel 303 is connected to the central shaft key to ensure the connection strength.

[0033] Regarding the design of the transmission mechanism 302, the transmission mechanism includes a main pulley, a driven pulley, and a belt. The main pulley is located on the output shaft of the motor 301, and the driven pulley is located at one end of the central shaft on the same side as the motor, between the friction wheel 303 and the bearing housing. The belt is fitted onto the main pulley and the driven pulley and is arranged parallel to the fixed plate 401.

[0034] Preferably, the belt is disposed at one end of the friction wheel 303.

[0035] See Figure 1 The fixing plate 401 is an obliquely arranged plate structure, parallel to the side of the track. The first spring 402 is located between the fixing plate 401 and the horizontal support 103, and its upper and lower ends are respectively connected to the middle position of the fixing plate 401 and the horizontal support 103 through the second connecting plate.

[0036] An L-shaped fixing seat is set on the base 2, with one end fixed parallel to the base 2 and the other end set vertically, and is rotatably connected to the fixing plate 401 by bolts.

[0037] In this embodiment, the second connecting plate is an L-shaped bent plate. One end of each of the two second connecting plates is connected to the opposite side of the fixed plate 401 and the horizontal bracket 103, respectively, and the other end extends towards the opposite side. The center lines of the two second connecting plates are located on the same plane, which facilitates connection with the first spring by bolts.

[0038] The bolt is detachably connected to the opposite surface of the second connecting plate, and its position on the second connecting plate is adjustable. Its end is provided with an opening for connecting the hooks at both ends of the first spring.

[0039] Furthermore, the first spring 402 is located between the two second pulleys, without contacting any components in between; its specific installation position can be confirmed during use. The second connecting plate is vertically oriented with one end wider than the other, and it is secured with two bolts to increase its stability.

[0040] See Figure 6In this invention, a sliding contact line is provided above the track, and a current collector is provided at the upper end of the upper support 102. The two are in contact and provide power to the device through a wire. The current collector can be located on the outer side of the upper end of the upper support 102, extending upward to contact the sliding contact line.

[0041] A smart monitoring terminal is installed on base 2. The system can automatically activate the radar to scan the materials accumulated in the hopper and transmit the data to the computer system. The computer system processes the scanned data, calculates the volume of the materials in the hopper, and calculates the weight based on the density. Since the automatic stopping and starting of the device, as well as the scanning of materials and data processing by computer, are existing technologies—for example, Chinese utility model CN218601465U uses a central control box to control the movement of the trolley and uses radar to scan materials—this will not be elaborated upon further.
