Description
Technical Field
[0001] This utility model relates to the field of concrete chute technology, specifically a mobile concrete chute that can be flexibly adjusted. Background Technology
[0002] Concrete pouring is a crucial step in construction engineering. After mixing the concrete, the mixer truck discharges it. However, due to the influence of terrain and buildings or structures, there is often a long distance and significant height difference between the mixer truck's discharge port and some pouring objects, making direct pouring difficult. Furthermore, the location and volume of concrete in these pouring objects make it unsuitable for use with overhead pumps or cranes. To address this problem, concrete chutes have been developed, which can smoothly guide concrete into the pouring object, thus completing the pouring process. However, traditional methods use simple chutes for concrete pouring. Simple chutes have a fixed structure, cannot be flexibly adjusted, are generally not reusable, and require significant manpower and time to move, resulting in low construction efficiency and affecting pouring quality. Even with foldable chute structures, their stability is poor, and the chutes themselves lack strength, making them prone to deformation. Therefore, there is an urgent need for a flexible, adjustable, mobile concrete chute for concrete pouring operations in construction engineering. Utility Model Content

One end of the upper telescopic part is rotatably connected to the inner wall of the mounting groove and locked by a first positioning member. The other end of the upper telescopic part enters and exits the mounting groove and is rotatably connected to one end of the lower support part. The upper telescopic part and the lower support part are locked by a second positioning member.
[0008] As a further technical solution, the upper telescopic part includes a first telescopic rod, a plurality of second telescopic rods, and a third telescopic rod. One end of the first telescopic rod is rotatably connected to the inner wall of the mounting groove. The plurality of second telescopic rods and the third telescopic rod are slidably sleeved on the other end of the first telescopic rod in sequence. The end of the third telescopic rod away from the first telescopic rod is rotatably connected to the lower support part. A plurality of first positioning holes are arranged along the length direction on the side walls of the first telescopic rod, the plurality of second telescopic rods, and the third telescopic rod.

[0014] As a further technical solution, the second positioning component includes a second connecting rod, one end of which is connected to the third telescopic rod by a bolt, and the other end is connected to the lower support by a bolt.
[0015] As a further technical solution, the groove includes a first groove, a second groove and a third groove, one end of the second groove is slidably connected to the first groove, and the other end is rotatably connected to the third groove via a hinge;
[0016] The mounting slot includes a first mounting slot and a second mounting slot. The first mounting slot is disposed on the first slot body, and the second mounting slot is disposed on the second slot body. One end of the second mounting slot is slidably connected to one end of the first mounting slot and is locked by bolts.
[0017] The first support leg consists of four sets, two of which are symmetrically arranged on both sides of the first groove, with one end rotatably connected to the inner wall of the first mounting groove away from the second mounting groove. The other two sets are symmetrically arranged on both sides of the second groove, with one end rotatably connected to the inner wall of the second mounting groove away from the first mounting groove.

[0023] This utility model has a simple structure. In use, the upper telescopic parts and lower support parts of multiple sets of first legs are rotated to a vertical position and locked by the first and second positioning parts, respectively, thereby supporting the trough. At the same time, the side wall of the mounting trough can act as a reinforcing rib, thereby increasing the strength of the trough and preventing deformation. During transportation, the upper telescopic parts of multiple sets of first legs are simply retracted into the mounting trough, so that the lower support part is perpendicularly connected to the upper telescopic part. The trough is supported only by the lower support part to prevent it from tipping over, effectively reducing the volume of the entire concrete chute and making it easy to transport and store.

[0031] like Figures 1-5 As shown, this utility model provides a mobile concrete chute that can be flexibly adjusted, mainly including a chute body 1, a first support leg 3, and a second support leg 8.
[0032] The trough 1 includes a first trough 101, a second trough 102, and a third trough 103. One end of the second trough 102 is slidably connected to the first trough 101, and the overall length of the trough 1 can be adjusted according to actual needs. The other end is rotatably connected to the third trough 103 via a hinge. The third trough 103 can rotate 90 degrees and has two states. When in use, the third trough 103 is attached to one end of the second trough 102. When not in use, the third trough 103 is clipped onto the top of the second trough 102, which helps to save space. The free end of the third trough 103 is the discharge port. The two sides of the discharge port have a specific curved profile, forming a guide part 11, which is used to guide the material to flow smoothly out of the equipment. The outer walls on both sides of the trough 1 are symmetrically provided with mounting grooves 2. The openings of the mounting grooves 2 are opposite to the openings of the trough 1. Specifically, the mounting grooves 2 include a first mounting groove 21 and a second mounting groove 22. The first mounting groove 21 is provided on both sides of the first trough 101, and the second mounting groove 22 is provided on both sides of the second trough 102. One end of the second mounting groove 22 is slidably connected to one end of the first mounting groove 21. A plurality of third positioning holes 12 are arranged on one side wall of the first mounting groove 21 and one side wall of the second mounting groove 22. Any third positioning hole 12 on the first mounting groove 21 coincides with any third positioning hole 12 on the second mounting groove 22 and is locked with bolts. This facilitates the expansion and contraction of the first trough 101 and the second trough 102, thereby adjusting the length of the chute. After adjusting the expansion and contraction length, the chute is locked. The structure is simple and easy to operate.
[0033] The first support leg 3 consists of multiple sets symmetrically arranged on both sides of the tank 1. In this embodiment, there are four sets of the first support leg 3. Two sets of the first support leg 3 are symmetrically arranged on both sides of the first tank 101, with one end rotatably connected to the inner wall of the end of the first mounting groove 21 away from the second mounting groove 22. The other two sets of the first support leg 3 are symmetrically arranged on both sides of the second tank 102, with one end rotatably connected to the inner wall of the end of the second mounting groove 22 away from the first mounting groove 21. This symmetrical arrangement ensures the stability and balance of the tank 1. Specifically, each set of first support legs 3 includes an upper telescopic part 31 and a lower support part 32. The upper telescopic part 31 is used to be housed in the mounting groove 2. The upper telescopic part 31 includes a first telescopic rod 311, several second telescopic rods 312, and a third telescopic rod 313. One end of the first telescopic rod 311 is rotatably connected to the inner wall of the mounting groove 2 and locked by a first positioning member 4. Several second telescopic rods 312 and third telescopic rods 313 are slidably sleeved on the other end of the first telescopic rod 311 in sequence. The end of the third telescopic rod 313 away from the first telescopic rod 311 is rotatably connected to the lower support part 32 and locked by a second positioning member. Several first positioning holes 5 are arranged along their length on the side walls of the first telescopic rod 311, several second telescopic rods 312, and third telescopic rod 313. Any first positioning hole 5 on the first telescopic rod 311, any first positioning hole 5 on several second telescopic rods 312, and any first positioning hole 5 on the third telescopic rod 313 coincide with each other and are locked by bolts. By pushing and pulling the first telescopic rod 311, the second telescopic rod 312, and the third telescopic rod 313 and locking the overlapping first positioning hole 5 with bolts, the length of the upper telescopic part 31 can be flexibly adjusted, thereby realizing the adjustment of the height and angle of the tank 1.
[0034] In this invention, the top of the lower support 32 and the bottom of the third telescopic rod 313 are connected by a bolt as a pivot. When the nut of the bolt is loosened, the lower support 32 and the third telescopic rod 313 are rotatably connected. After rotating to the appropriate position, the nut of the bolt is tightened. Using a bolt as a pivot not only realizes the rotatable connection between the lower support 32 and the third telescopic rod 313, but also improves the convenience of locking and disassembling operations between the two. In addition, the lower support 32 is a sleeve rod, which can be sleeved on the third telescopic rod 313. Multiple fourth positioning holes 14 are arranged on the side wall of the lower support 32. When installing the chute, the lower support 32 can be removed from the third telescopic rod 313 as needed, and then slidably sleeved on the lower end of the third telescopic rod 313, so that any fourth positioning hole 14 coincides with any first positioning hole 5 on the third telescopic rod 313, and then tightened with a bolt, thereby further adjusting the length of the entire first leg 3.
[0035] The second positioning component includes a second connecting rod 6. One end of the second connecting rod 6 is connected to the third telescopic rod 313 by bolts, and the other end is connected to the lower support part 32 by bolts. When the upper telescopic part 31 is retracted into the mounting groove 2, the second positioning component can vertically lock the lower support part 32 onto the third telescopic rod 313. This helps to further limit the position of the lower support part 32 on the basis of the bolt lock between the lower support part 32 and the third telescopic rod 313, preventing the lower support part 32 from deflecting. When the chute is in use, the second connecting rod 6 and the bolts at both ends can be removed. At this time, the lower support part 32 can be sleeved on the outside of the third telescopic rod 313 and locked with bolts, or the lower support part 32 can be rotated to a collinear state with the third telescopic rod 313 and locked with bolts.
[0036] The bottom outer wall of the first trough 101 is provided with a third mounting groove 7. The two side walls of the third mounting groove 7 serve as reinforcing ribs, enhancing the overall strength of the first trough 101. A second support leg 8 is housed within the third mounting groove 7. One end of the second support leg 8 is rotatably connected to the inner wall of the third mounting groove 7 near the second trough 102 and locked by a first positioning member 4. The other end of the second support leg 8 extends into and exits within the third mounting groove 7. The second support leg 8 provides support at the junction of the first trough 101 and the second trough 102, further enhancing the strength of the trough 1 and the stability of the entire chute. Specifically, the second support leg 8 includes multiple fourth telescopic rods 81 that are slidably connected in sequence. Multiple second positioning holes 9 are arranged along the length of the side wall of each fourth telescopic rod 81. Any of the second positioning holes 9 on the multiple fourth telescopic rods 81 overlap and are locked by bolts. The multiple fourth telescopic rods 81 allow for adjustment of the length of the second support leg 8 as needed.
[0037] The first positioning component 4 includes a slide rail 41, a slider 42, and a first connecting rod 43. The slide rail 41 is fixedly mounted on the side wall of the first mounting groove 21, the second mounting groove 22, or the third mounting groove 7. The slider 42 is slidably mounted on the slide rail 41 and locked with bolts. One end of the first connecting rod 43 is rotatably connected to the slider 42, and the other end is rotatably connected to the side wall of the first telescopic rod 311 or the fourth telescopic rod 81. The first positioning component 4 allows for adjustment and locking of the rotation angle of the first telescopic rod 311 and the fourth telescopic rod 81. The slide rail 41 is provided with graduations to facilitate accurate control of the rotation angle of the upper telescopic part 31 by the operator.
[0038] The bottom of the lower support 32 is equipped with a caster wheel 10 with a brake, and the bottom of the fourth telescopic rod 81 at the lowest end is also equipped with a caster wheel 10 with a brake. The caster wheel 10 facilitates the movement of the chute, while the braking device can fix the chute after it reaches the designated position, ensuring the safety and stability of the construction process. When the upper telescopic part 31 is retracted into the mounting groove 2 and the second support leg 8 is retracted into the third mounting groove 7, the height of the caster wheel 10 on the second support leg 8 is the same as the height of the caster wheel 10 on the lower support 32. This allows the chute to move even in the retracted state using the caster wheel 10 of the lower support 32 and the caster wheel 10 of the second support leg 8, further enhancing the stability of the movement.
[0039] In this invention, each upper telescopic part 31 is equipped with a fixing rod 13 by bolts. When the chute is in the retracted position, the fixing rod 13 retracts along the length of the upper telescopic part 31. When the chute is in use, the fixing rod 13 is rotated and one end of the two fixing rods 13 located on both sides of the chute body 1 is locked together by bolts. Figure 5 As shown, this further ensures the stability of the chute during use.
[0040] The specific steps for using this utility model are as follows:
[0041] During transport, the chute is in a retracted state, such as Figure 2 and Figure 3 As shown in the diagram, the second trough 102 is retracted into the first trough 101, the third trough 103 is fastened above the second trough 102, the upper telescopic part 31 is retracted into the mounting slot 2, the lower support part 32 is vertically connected to the upper telescopic part 31 through the second connecting rod 6, and the second support leg 8 is retracted into the third mounting slot 7. At this time, the universal wheel 10 below the lower support part 32 is at the same height as the universal wheel 10 below the fourth telescopic rod 81. The trough can be moved and transported simply by pushing it.
[0042] In use, the second connecting rod 6 is removed, the lower support 32 is rotated to be collinear with the upper telescopic part 31 and fixed, then the bolts on the slider 42 are loosened and the four first legs 3 are rotated to a vertical position respectively; the bolts on the third positioning hole 12 are loosened, the second trough 102 is pulled out from the first trough 101, and the third trough 103 is rotated 90 degrees so that the third trough 103 is connected to the end of the second trough 102. The overall length of the first trough 101, the second trough 102 and the third trough 103 is determined as needed, and then bolted onto the two overlapping third positioning holes 12; then the height and angle of the chute are adjusted by adjusting the telescopic length of the upper telescopic part 31 so that one end of the chute is at the same height and connected to the discharge port of the mixer truck, and the other end is located directly above the construction surface of the poured material. First, loosen the bolts on the first positioning holes 5, pull out the first telescopic rod 311, the second telescopic rod 312, and the third telescopic rod 313. When the required length is reached, tighten the bolts on the overlapping first positioning holes 5. Then, according to the scale on the slide rail 41, slide the slider 42 to the appropriate position, and then tighten the slider 42 with bolts, thereby changing the angle between the upper telescopic part 31 and the mounting groove 2, and also locking the top of the first telescopic rod 311 to the chute. Finally, loosen the bolts on the slider 42 at the top of the second support leg 8 and the bolts on the second positioning hole 9, rotate the second support leg 8 out of the third mounting groove 7, and adjust the second support leg 8 to the required length by pulling out the fourth telescopic rods 81. Then, tighten the bolts on the second positioning hole 9 and the bolts on the slider 42 in sequence, thus completing the entire chute's unfolding adjustment and achieving the desired result. Figure 1 As shown in the unfolded state, the brake of the universal wheel 10 locks the universal wheel 10 to prevent the chute from moving.
[0043] After use, restore the chute from its expanded state to its contracted state.
[0044] This invention, by incorporating a retractable upper telescopic part 31 and a second support leg 8, as well as a slidably connected first trough body 101 and second trough body 102, allows for flexible adjustment of the chute's length, height, and angle according to the actual needs of the construction site. Operators can quickly and accurately adjust the chute based on factors such as the height difference and horizontal distance between the mixer truck's discharge port and the pouring position, improving construction adaptability and efficiency. Both the lower support part 32 and the ends of the second support leg 8 are equipped with casters 10 with brakes, facilitating the movement and positioning of the chute on the construction site. Construction personnel can easily move the chute to the desired position and secure it using the braking device, reducing manual handling and lowering construction costs. Furthermore, the first mounting groove 21, the second mounting groove 22, and the third mounting groove 7 act as reinforcing ribs, enhancing the overall strength of the trough body 1.
