Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, and in particular to a grabbing, transporting and paving device for masonry stones in irrigation canals. Background Technology

[0002] Irrigation canals are waterways connecting irrigation sources to irrigated land. They transport and distribute water drawn from the source to various parts of the irrigated area. During the water transport process, only a portion of the water is delivered to the fields for crop use through the various levels of canals, while the remaining water seeps into the soil along the canal through the pores of the canal bottom and slopes, failing to reach the farmland for crop use. This is canal seepage loss. Canal seepage prevention engineering technology refers to various engineering techniques adopted to reduce the permeability of the canal bed soil or to establish a water-impermeable protective layer. Constructing a seepage-proof revetment on the canal bed surface, with masonry revetment being suitable for mountainous canals where stone materials are available, can utilize local materials. If the construction quality is good, canal seepage can be reduced by approximately 80% to 90%. However, in mountainous or sloping areas, manual handling of stones is still necessary. Existing stone slab clamps cannot be adjusted according to different sizes of stone slabs, thus limiting their use and failing to meet the requirements for clamping different sized stone slabs.

[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 with reference to the accompanying drawings. 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] A grabbing, transporting, and paving device for masonry stones in irrigation canals, combined with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the device includes: a horizontal rod structure 1, a support rod structure 2, and a clamping part 3. The horizontal rod structure 1 is connected to the support rod structure 2, and the support rod structure 2 is connected to the clamping part 3. The clamping part 3 includes two sets of clamping arm assemblies, each comprising: a clamping arm 32, a clamping telescopic assembly, and a clamping claw 33. The clamping arm 32 is rotatably connected to the support rod structure 2, and the clamping telescopic assembly adjusts the position of the clamping claw 33 along the length of the clamping arm 32. Under the influence of their own weight and the weight of the stone slab material, the two sets of clamping arm assemblies tighten downwards. This downward force effectively clamps the stone slab material, thus completing the gripping operation. This application achieves adjustment according to different sizes of the stone slab material by setting the clamping telescopic assembly to adjust the position of the clamping claw 33 along the length of the clamping arm 32. Therefore, this application achieves the following: when clamping wider stone slabs, the clamping arm angle of 32° is not excessive; when clamping narrower stone slabs, it does not require lifting to a very high position to clamp them; and when clamping very narrow stone slabs, it avoids situations where it cannot be lifted. This application has the ability to adapt to multiple specifications of stone slabs, improving operational flexibility and facilitating efficient use in different situations, which is conducive to improving the grabbing, transportation, and paving efficiency of masonry in irrigation canals.

[0025] Preferably, the clamping telescopic assembly includes: a sliding groove formed on the clamping arm 32, a row of circular holes formed on the side wall of the sliding groove, a connector 34 fixed on the clamping claw 33, and a spring pin; the connector 34 slides along the sliding groove, and spring pins are provided on both sides of the connector 34, with the spring pins engaging in the circular holes to fix the position of the connector 34. Pressing the spring pins disengages them from the circular holes, and then the connector 34 slides in the sliding groove of the clamping arm 32 to a suitable position, before the spring pins engage in the circular holes for positioning. Furthermore, the sliding groove can be designed as a T-shaped groove, and the portion of the connector 34 located within the sliding groove is designed as a matching "T" shape, thereby achieving sliding guidance of the connector 34 and improving its load-bearing capacity.

[0026] Preferably, the end of the gripping arm 32 is provided with a rotating hole 31, and the gripping arm 32 is rotatably connected to the support rod structure 2 through the rotating hole 31 and the rotating shaft 23, so as to ensure that the gripping arm 32 can rotate freely under the action of gravity and is easy to store.

[0027] Preferably, the support rod structure 2 includes: a support rod 21, a connecting assembly 22, and a locking nut; the connecting assembly 22 connects the support rod 21 and the clamping arm 32; the upper end of the support rod 21 is threaded, and the upper end of the support rod 21 passes through the horizontal rod structure 1 and is connected to the locking nut. When two operators lift the horizontal rod structure 1, the locking nut restricts the lifting of the support rod 21, and then the support rod 21 lifts the clamping part 3 through the connecting assembly 22.

[0028] Preferably, the connecting assembly 22 includes an upper connector and a lower connector. The upper connector is fixedly disposed at the lower end of the support rod 21, and the insertion section of the lower connector is inserted into the insertion hole of the upper connector. The lower connector and the upper connector are detachably and fixedly connected. During normal use, the upper connector and the lower connector are connected to meet the needs of normal operation; after use, the upper connector and the lower connector can be separated for easy storage and carrying.

[0029] Specifically, after the lower connector's insertion segment is inserted into the upper connector's insertion hole, the upper connector and the lower connector are connected by bolts.

[0030] Specifically, the connecting section of the lower connector has rotating holes at both ends. After the rotating hole 31 at the end of the clamping arm 32 is aligned with the rotating hole, the rotating shaft 23 passes through the rotating hole 31 and the rotating hole and then a limiting component is installed to prevent it from coming out. The limiting component is detachable, such as a lock nut, cotter pin, quick-lock pin, or shaft retaining ring. The limiting component ensures the safety of the clamping arm 32 rotating freely during operation, and can be disassembled after use for easy storage of the clamping arm 32.

[0031] Preferably, the outer diameter of the support rod 21 body is larger than the major diameter of the thread, thus forming a first stepped surface. The support rod 21 body rotatably passes through the horizontal rod structure 1, and the locking nut abuts against the first stepped surface. A cross auxiliary handle 25 is fixed on the locking nut. In use, the cross auxiliary handle 25 can be rotated with one hand, easily driving the support rod 21 below to rotate. In actual operation, the rotation should be performed in the tightening direction of the locking nut to prevent the locking nut from loosening. The cross auxiliary handle 25 allows for flexible adjustment of the direction and angle of the stone slab material clamped by the clamped part 3 to meet actual needs; it avoids the operator having to laboriously lift the entire device to adjust the direction when the orientation of the stone slab material is not correct, which helps to reduce workload and improve work efficiency.

[0032] Preferably, the horizontal rod structure 1 includes: a hollow inner rod 11, a hollow outer sleeve 14, and several spring buckles 15; a row of first positioning holes is formed axially on the wall of the outer sleeve 14, and a row of second positioning holes is formed axially on the wall of the inner rod 11. The spring buckles 15 are installed inside the inner rod 11, and the two inner rods 11 are inserted from both ends of the outer sleeve 14. The ball of the spring buckle 15 passes through the second positioning hole and engages with the first positioning hole to position the inner rod 11. In use, the inner rod 11 is slowly pulled outward. As the inner rod 11 is pulled out, the second positioning hole aligns with the first positioning hole, and the ball of the spring buckle 15 pops out under the action of the internal spring piece, accurately engaging with the first positioning hole to fix the position of the inner rod 11. When adjustment is required, the ball of the spring buckle 15 is pressed down to retract into the second positioning hole, and then the inner rod 11 is pushed or pulled until the length of the horizontal rod structure 1 is adjusted to a suitable length. After use, press the ball of the spring buckle 15 to retract it into the second positioning hole, and then push the inner rod 11 to compress it and store it in the outer sleeve 14, thereby greatly shortening the overall length of the horizontal rod structure 1 and achieving the purpose of portability.

[0033] Preferably, the ball of the spring buckle 15 is a solid structure to improve the load-bearing capacity, such as using a solid ball or inserting a solid iron column inside the ball.

[0034] Preferably, the outer sleeve 14 has two rows of opposing first positioning holes along the axial direction on its tube wall, and the inner rod 11 has two rows of opposing second positioning holes along the axial direction on its tube wall. The spring buckle 15 is a V-shaped double-ball spring buckle. The two rows of first positioning holes correspond to the two rows of second positioning holes, and the two balls of the V-shaped double-ball spring buckle correspond to one row of second positioning holes for positioning. The balls of the spring buckle 15 play a crucial supporting and fixing role, ensuring that the horizontal rod structure 1 is firmly fixed to the inner rod 11 after being adjusted to the appropriate length, without loosening or sliding, thereby ensuring stability and safety during use.

[0035] Specifically, a central hole 13 is provided in the middle of the outer sleeve 14. The main body of the support rod 21 includes a support section and a rotating section. The outer diameter of the rotating section is smaller than that of the support section, thus forming a second stepped surface. A threaded section is provided at the top of the rotating section. The outer diameter of the threaded section is smaller than that of the rotating section, thus forming a first stepped surface. The rotating section is inserted into the central hole 13, and the lower part of the outer sleeve 14 abuts against the second stepped surface. The threaded section passes through the central hole 13, and the first stepped surface is exposed above the outer sleeve 14. External threads are machined on the threaded section, and the locking nut is screwed onto the threaded section and abuts against the first stepped surface. Under the action of gravity, the lower end of the locking nut abuts against the upper part of the outer sleeve 14, thereby allowing the support rod structure 2 and the clamping part 3 to be lifted by lifting the outer sleeve 14, and enabling convenient disassembly and storage.

[0036] Preferably, a rubber handle 12 is fitted onto the end of the inner rod 11 away from the outer sleeve 14, which improves grip and comfort, has a good anti-slip effect, and prevents slippage and injury; at the same time, it can reduce pressure on the hand and prevent fatigue and discomfort caused by prolonged holding during use. Furthermore, the rubber handle 12 can be shaped to fit the palm; and the cost of rubber material is relatively low, which can reduce manufacturing costs.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
