Description

Technical Field

[0001] This utility model relates to the technical field, and more specifically to a one-time forming tool for T-shaped channel excavation. Background Technology

[0002] Canals typically refer to irrigation and drainage waterways excavated around rivers, lakes, or reservoirs. A T-shaped canal is a type of canal with a T-shaped cross-section, a wider bottom, and two narrower sidewalls. Because of its narrower bottom, it can better control the water flow speed and is more suitable for discharging small amounts of water. During the excavation of a T-shaped canal, a gantry crane is needed to pull a one-piece excavation tool to achieve rapid excavation.

[0003] Existing one-piece forming tools are usually directly assembled with equipment such as cranes. When the crane travels over undulating ground, the tool will also undulate, causing the T-shaped channel to be excavated unevenly. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a one-time forming tool for T-shaped channel excavation. When the vehicle passes over undulating ground, the height and position of the forming mold can be adjusted to prevent uneven T-shaped channel excavation caused by the height and position of the forming mold, thus ensuring the excavation quality of the T-shaped channel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tool for one-step excavation of a T-shaped channel includes:

[0007] Forming molds are used to shape the outline of T-shaped channel channels;

[0008] The distance sensor is detachably mounted on the molding die and remains relatively stationary with respect to the molding die. It is used to detect the height distance between the detection end and the bottom surface of the channel in real time.

[0009] The height compensation mechanism is detachably assembled on the trolley. The forming mold is detachably hoisted by the traction component and pulled by the trolley along the channel axis. The height position of the forming mold is adjustable by the traction component.

[0010] The structural features of this utility model also lie in:

[0011] A pair of distance sensors are provided, symmetrically positioned on the top of the forming mold along the width of the channel.

[0012] The height compensation mechanism includes a vertical plate and a pair of traction components symmetrically arranged on the vertical plate along the channel width direction. The height compensation mechanism is detachably assembled on the trolley via the vertical plate. The traction components include a vertical hole formed on the vertical plate, as well as a connecting rod, a connecting shaft, a limiting plate, a connecting piece, and an electric cylinder. The connecting shaft passes through the vertical hole and can slide up and down along the vertical hole. The two ends of the shaft are respectively fitted with connecting rings and limiting plates. The connecting rings and limiting plates are close to the vertical plate. The forming mold is detachably hoisted by the connecting rods of the pair of traction components. The tops of the pair of connecting rods respectively form the connecting rings. The mounting end of the electric cylinder faces upward and is hinged to the mounting seat on the vertical plate. The actuating end faces downward and is hinged to the connecting piece on the connecting shaft. Both hinged shafts are parallel to the connecting shaft and arranged along the channel axis. The extension and retraction of the electric cylinder pulls the connecting shaft to slide back and forth vertically along the vertical hole, driving the connecting rod and the forming mold to rise and fall synchronously.

[0013] A pair of connecting rods are located on the same side of the vertical plate, and a pair of electric cylinders are located on the outside of the pair of connecting rods, with the actuators facing downwards and tilted towards the connecting shaft.

[0014] The height compensation mechanism also includes a roller assembly. Each connecting rod is equipped with at least one set of roller assemblies. The roller assembly includes a mounting frame and a roller rotatably mounted on the mounting frame. The outer circumferential surface of the roller contacts the side wall of the connecting rod and can rotate around the central axis of the roller body by the friction force generated between the roller and the connecting rod.

[0015] The connecting ring and the limiting plate are respectively fitted onto the end of the connecting shaft with an interference fit.

[0016] Compared with existing technologies, the beneficial effects of this utility model are reflected in:

[0017] This invention utilizes a height compensation mechanism in conjunction with a distance sensor. The distance sensor, which remains relatively stationary with respect to the forming mold, monitors the height distance between its detection end and the bottom of the channel in real time, thereby determining the height position of the forming mold. When the vehicle encounters undulating road surfaces, causing the height position of the forming mold to change, the height compensation mechanism pulls the forming mold upward or downward in a linear displacement, thereby adjusting the height position of the forming mold and restoring it to the set height position. This prevents unevenness in the excavation of the T-shaped channel due to the influence of the forming mold's height position, ensuring the excavation quality of the T-shaped channel.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please refer to Figures 1 to 4 The T-shaped channel excavation tool in this embodiment includes:

[0025] Molding mold 1, used to form the shape of the T-shaped channel trough;

[0026] Distance sensor 2 is detachably mounted on molding mold 1 and remains relatively stationary with molding mold 1, and is used to detect the height distance between the detection end and the bottom surface of the channel in real time;

[0027] The height compensation mechanism is detachably assembled on the trolley. The forming mold 1 is detachably hoisted by the traction component and pulled by the trolley along the channel axis. The height position of the forming mold 1 is adjustable by the traction component.

[0028] In practice, the corresponding structural design of this one-time molding tool also includes:

[0029] The outer contour of the forming mold 1 is adapted to the cross-sectional shape of the T-shaped channel. The two side edges 11 are used to form the two side walls of the T-shaped channel, the bottom edge 12 is used to form the bottom of the T-shaped channel, and the flanges 13 extending from the top to both sides are used to extrude and form the channel while pressing it.

[0030] A pair of distance sensors 2 are provided, symmetrically positioned on the top of the forming mold 1 along the channel width direction. They are detachably assembled onto the forming mold 1 via bolts using sensor mounting brackets 1021.

[0031] The height compensation mechanism includes a vertical plate 3 and a pair of traction components symmetrically arranged on the vertical plate 3 along the channel width direction. The height compensation mechanism is detachably assembled onto the traveling vehicle via the vertical plate 3. The traction components include a vertical hole 31 formed on the vertical plate 3, as well as a connecting rod 4, a connecting shaft 5, a limiting plate 6, a connecting piece 7, and an electric cylinder 8. The connecting shaft 5 passes through the vertical hole 31 and can slide up and down along the vertical hole 31. The two ends of the shaft are respectively fitted with connecting rings 41 and limiting plates 6, which are adjacent to the vertical plate 3. The forming mold 1 is detachably hoisted by a pair of connecting rods 4 of the traction components. The top of the pair of connecting rods 4 respectively forms a connecting ring 41. The mounting end of the electric cylinder 8 faces upward and is hinged to the mounting seat 9 on the vertical plate 3. The execution end faces downward and is hinged to the connecting part 7 on the connecting shaft 5. Both hinge shafts are parallel to the connecting shaft 5 and arranged along the channel axis. The extension and retraction of the electric cylinder 8 pulls the connecting shaft 5 to slide vertically back and forth along the vertical hole 31, driving the connecting rod 4 and the forming mold 1 to rise and fall synchronously.

[0032] Mounting element 12 is provided on the vertical plate 3 at the position for assembly with the crane. The mounting element 12 is detachably assembled with the crane. The detachable assembly can be in the form of bolt connection.

[0033] A pair of connecting rods 4 are located on the same side of the vertical plate 3, and a pair of electric cylinders 8 are located on the outside of the pair of connecting rods 4, with the actuators facing down and tilted towards the connecting shaft 5.

[0034] The bottom end of the connecting rod 4 is detachably fastened to the top end of the forming mold 1 by bolts.

[0035] The height compensation mechanism also includes roller 11 assemblies. Each connecting rod 4 is equipped with at least one set of roller 11 assemblies. The roller 11 assembly includes a mounting frame 10 and rollers 11 rotatably mounted on the mounting frame 10. The mounting frame 10 is detachably mounted on the vertical plate 3 by bolts. The outer circumferential surface of the roller 11 contacts the side wall of the connecting rod 4, and it can rotate around the central axis of the wheel body by the friction generated between it and the connecting rod 4. The central axis of the roller 11 is horizontal and parallel to the central axis of the connecting shaft 5. The rollers 11 ensure that the two connecting rods 4 always move vertically, preventing the molding die 1 from tilting when it is lifted and lowered by the traction assembly.

[0036] The connecting ring 41 and the limiting plate 6 are respectively fitted onto the shaft end of the connecting shaft 5 with an interference fit. The outer diameter of both is larger than the width of the vertical hole 31, and they are used to limit the axial displacement of the connecting shaft 5.

[0037] Both the electric cylinder 8 and the distance sensor 2 are electrically connected to a controller. The controller controls the electric cylinder 8 to move based on the comparison result between the detection signal received from the distance sensor 2 and the preset signal. The detection signal of the distance sensor 2 is the real-time height distance between the detection end and the bottom surface of the channel, and the preset signal is the set height distance between the detection end and the bottom surface of the channel. When it is the set height distance, the forming mold 1 is at the set height position for excavating the T-shaped channel.

[0038] The following is an application example of the T-shaped channel excavation one-step forming tool in this embodiment:

[0039] The crane travels on the ground above the channel, and the crane drives the height compensation mechanism and the forming mold 1 hoisted by it to move together along the channel axis. The moving forming mold 1 is used to form the shape of the channel, and the T-shaped channel is excavated in one step.

[0040] When the vehicle encounters an uneven road surface, the height of the forming mold 1 will change with the undulation of the vehicle. If it is not corrected in time, the bottom surface of the excavated T-shaped channel will be uneven. In this embodiment, when the vehicle passes over an uneven road surface, the distance sensor 2, which is relatively stationary with respect to the forming mold 1, will detect a change in the distance between its detection end and the bottom surface of the T-shaped channel. At this time, the extension / retraction of the electric cylinder 8 can drive the connecting shaft 5 to move up / down along the vertical hole 31. The connecting shaft 5, along with the connecting rod 4, pulls the forming mold 1 to move up / down synchronously, adjusting the height of the forming mold 1 so that it can maintain a set height position and travel along the channel axis, preventing the T-shaped channel from being excavated unevenly due to the influence of the height of the forming mold 1.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
