Description

Technical Field

[0001] This utility model relates to the field of dam gate slot measurement technology, and in particular to a measuring trolley for measuring dam gate slots. Background Technology

[0002] Hydropower stations, reservoirs, and other water conservancy projects are generally equipped with gates to intercept water flow, control water levels, regulate flow, and discharge silt and floating debris. When the gate slot support track spacing does not meet design requirements due to mountain deformation or improper installation, the gate will vibrate during opening and closing, accelerating the aging and damage of components, reducing the service life of the opening and closing equipment, and in severe cases, even causing the gate to jam, affecting the safe operation of the facility. When the gate vibrates or jams, maintenance personnel will measure the gate slot support track spacing and develop corresponding solutions based on the measured data. The accuracy of the spacing measurement directly affects the quality of equipment maintenance.

[0003] According to patent application number 202223055751.2, entitled "A Gate Slot Spacing Measuring Tool," the patent includes a housing, within which are a first cavity and a second cavity. The cross-sectional dimension of the second cavity is larger than that of the first cavity. A telescopic ruler is provided within the housing, comprising a rod that engages with the first cavity. A measuring rod is located at the end of the rod and is positioned within the second cavity. A spring is fitted onto the rod and positioned between the end of the measuring rod and the bottom of the second cavity. The measuring rod has graduations. This measuring tool is used to measure the distance between the gate slot support rails, providing accurate and reliable data support for the inspection and maintenance of the gate and its slots.

[0004] Although the aforementioned patent can measure the distance between the gate slot support rails, the tool requires manual operation to extend the measuring rod before measurement can be performed. Therefore, it is inconvenient to hold the tool to measure the distance between each position of the support rails, resulting in low reliability and low automation. Therefore, to address the above problems, a measuring trolley for measuring the gate slots of dam gates is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A measuring trolley for measuring the gate slot of a dam gate includes a fixed housing. A controller and a receiver, arranged vertically, are fixedly connected to the front end of the fixed housing. Laser rangefinders are fixedly connected to both the left and right ends of the inner side of the fixed housing. Worm gears are rotatably connected to both the upper and lower ends of the inner side of the fixed housing via rotating shafts. A support rod is fixedly connected to one end of the outer side of the worm gear. A battery is fixedly connected to the top of the fixed housing. A sleeve rod is slidably connected to one end of the outer side of the support rod. A spring is provided at one end of the inner side of the sleeve rod. A pressure block that contacts the sleeve rod is fixedly connected to one end of the spring. A pressure sensor that contacts the sleeve rod is fixedly connected to one end of the pressure block. A dual-axis motor with a self-locking mechanism is fixedly connected to the other end of the inner side of the sleeve rod. A roller is fixedly connected to the end of the main shaft of the dual-axis motor.

[0008] As a further improvement of this utility model, a worm is meshed with the other end of the outer side of the worm wheel, and the worm passes through the fixed shell, and the worm is rotatably connected to the fixed shell.

[0009] As a further improvement of this utility model, the outer side of the roller is provided with evenly distributed protrusions, and the protrusions on the outer side of the roller are arranged in a cone shape.

[0010] As a further improvement of this utility model, a signal light is provided at one end of the outer side of the sleeve, and the signal light is fixedly connected to the sleeve.

[0011] As a further improvement of this utility model, there are 8 rollers, and the rollers are symmetrically distributed.

[0012] As a further improvement of this utility model, the other end of the spring is fixedly connected to a fixing block that is slidably connected to the sleeve rod, and an electric push rod is fixedly connected to one end of the outer side of the fixing block, and the electric push rod is fixedly connected to the support rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. A measuring trolley for measuring the gate slot of a dam gate, comprising a worm gear, worm wheel, support rod, sleeve rod, pressure sensor, dual-axis motor, rollers, and laser rangefinder. When measuring the distance between the gate slot support rails, the worm gear is first rotated to engage the worm wheel. The support rod and sleeve rod then control the rollers at both ends to engage with the outer side of the support rails within the gate slot. At this time, a fixing block continuously compresses a spring, which in turn continuously presses against the pressure sensor. When the pressure sensor detects a pressure value within a set range, the dual-axis motor drives the rollers with protrusions on their outer sides to rotate. This further controls the laser rangefinders on both sides to continuously move upwards to measure the distance between the gate slot support rails. By securing the device between the gate slot support rails and then automatically controlling the laser rangefinders to continuously move upwards, combined with the data detected by the laser rangefinders on both sides and the dimensions of the fixing housing, the distance between each position on the gate slot support rails can be easily measured, improving the reliability and automation of the measurement process.

[0015] 2. A measuring trolley for measuring the gate slot of a dam gate, comprising an electric push rod, a fixed block, a pressure block, a pressure sensor, a sleeve rod, and a support rod. During the movement of the device along the gate slot support track by controlling the rotation of the rollers, when there is mud or pits in the gate slot, after the rollers reach this point, the sleeve rod slides outside the support rod, causing the fixed block to change position within the sleeve rod. This further changes the compression degree of the spring, thereby changing the pressure value sensed by the pressure sensor. The controller automatically controls the retraction and extension of the electric push rod, and by automatically controlling the retraction and extension of the electric push rod to reset the compression degree of the spring, the pressure value sensed by the pressure sensor under the pressure of the pressure block remains within the set range. This avoids jamming and slippage during the movement of the device, ensuring the normal measurement of the distance between the gate slot support tracks. Attached Figure Description

The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. In order to better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size.

Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figure 1-2 As shown, a measuring trolley for measuring the gate slot of a dam gate includes a fixed housing 1. A controller 2 and a receiver 3, arranged vertically, are fixedly connected to the front end of the fixed housing 1. Laser rangefinders 5 are fixedly connected to both the left and right ends of the inner side of the fixed housing 1. Worm gears 6 are rotatably connected to both the upper and lower ends of the inner side of the fixed housing 1 via rotating shafts. A support rod 7 is fixedly connected to one end of the outer side of the worm gear 6. A battery 9 is fixedly connected to the top of the fixed housing 1. A sleeve rod 10 is slidably connected to one end of the outer side of the support rod 7. A spring 11 is provided at one end of the inner side of the sleeve rod 10. A pressure block 12 that contacts the sleeve rod 10 is fixedly connected to one end of the spring 11. A pressure sensor 13 that contacts the sleeve rod 10 is fixedly connected to one end of the pressure block 12. A dual-axis motor 14 with a self-locking mechanism is fixedly connected to the other end of the inner side of the sleeve rod 10. A roller 15 is fixedly connected to the end of the main shaft of the dual-axis motor 14.

[0023] Example 2

[0024] like Figure 2 As shown, in order to solve the problem of the control device being difficult to support between the gate slot support rails, a worm 8 is meshed with the other end of the outer side of the worm wheel 6, and the worm 8 passes through the fixed shell 1. The worm 8 is rotatably connected to the fixed shell 1. By rotating the worm 8 to mesh with the worm wheel 6, it is convenient to support the control device between the gate slot support rails.

[0025] Example 3

[0026] like Figure 1-2As shown, in order to solve the problem of poor stability of the device when it is supported between the gate slot support rails, the outer side of the roller 15 is provided with evenly distributed protrusions, and the protrusions on the outer side of the roller 15 are set in a conical shape. When the device is supported between the gate slot support rails, the evenly distributed conical protrusions on the outer side of the roller 15 make the device more stable when it is supported between the gate slot support rails.

[0027] Example 4

[0028] like Figure 1-2 As shown, in order to solve the problem of not being able to determine whether the device has been tightened, a signal light 16 is provided at one end of the outer side of the sleeve rod 10, and the signal light 16 is fixedly connected to the sleeve rod 10. When the pressure value sensed by the pressure sensor 13 reaches the set range after the device is tightened between the gate slot support rails, the signal light 16 will light up, which makes it easier to determine whether the device has been tightened.

[0029] Example 5

[0030] like Figure 1-2 As shown, in order to solve the problem of possible displacement when the device moves, there are 8 rollers 15, and the rollers 15 are symmetrically distributed. When the device is supported between the gate slot support rails, the eight rollers 15 are respectively locked on the outside of the gate slot support rails on the left and right sides, thus avoiding the problem of possible displacement when the device moves.

[0031] Example 6

[0032] like Figure 2 As shown, in order to solve the problem of slippage and jamming of the device when there are pits and mud in the gate slot, the other end of the spring 11 is fixedly connected to a fixing block 17 that is slidably connected to the sleeve rod 10. An electric push rod 4 is fixedly connected to one end of the outer side of the fixing block 17, and the electric push rod 4 is fixedly connected to the support rod 7. When there are pits and mud in the gate slot, the controller 2 automatically controls the compression degree of the electric push rod 4 to retract and extend the return spring 11, so that the pressure value sensed by the pressure sensor 13 under the pressure of the pressure block 12 is always within the set range, avoiding slippage and jamming during the movement of the device.

[0033] In this embodiment, when measuring the distance between the gate slot support rails using the device, after the sensing range of the pressure sensor 13 is set by the controller 2, the worm 8 is first rotated to engage the worm wheel 6. Then, the support rod 7 and the sleeve rod 10 control the rollers 15 at both ends to lock onto the outside of the support rails within the gate slot. At this time, the fixing block 17 continuously compresses the spring 11, and the pressure block 12 continuously presses the pressure sensor 13. When the pressure value sensed by the pressure sensor 13 reaches the set range, the indicator light 16 illuminates. Then, the device is controlled by an external control mechanism. After the receiver 3 receives the control signal, the controller 2 controls the dual-axis motor 14 with a self-locking mechanism to drive the rollers 15 with protrusions on the outside to rotate. This further controls the laser rangefinders 5 on both sides to continuously move upwards to measure the distance between the gate slot support rails. At this time, by tightening the device between the gate slot support rails, the device is automatically controlled... The control device drives the laser rangefinder 5 to move upward continuously. Combining the data detected by the laser rangefinders 5 on both sides and the size of the fixed shell 1, it is convenient to measure the distance between each position of the gate slot support track. During the measurement operation, when there is mud or pit in the gate slot, after the roller 15 rotates to this position, the fixed block 17 changes position inside the sleeve rod 10 after sliding on the outside of the support rod 7 via the sleeve rod 10. This further changes the compression degree of the spring 11, thereby changing the pressure value sensed by the pressure sensor 13. The controller 2 automatically controls the electric push rod 4 to retract and extend. By automatically controlling the retraction and extension of the electric push rod 4 to reset the compression degree of the spring 11, the pressure value sensed by the pressure sensor 13 under the pressure of the pressure block 12 is always within the set range, avoiding jamming and slippage during the movement of the device, and ensuring the normal measurement of the distance between the gate slot support tracks.
