Description

Technical Field

[0001] The utility model relates to the technical field of vibro-impact construction equipment, in particular to a multi-point position-changing feeding device for vibro-impact pile construction. Background Art

[0002] The construction process of vibratory piles includes the hole-making stage and the pile-making stage. After the hole-making stage is completed, the pile-making stage begins. First, the vibratory equipment needs to drive the vibrator in the vibratory hole to lift up a certain distance, and then add a certain amount of material into the vibratory hole. After the material is added to the vibratory hole, the vibrator is driven downward to vibrate and compact the material. Then, the above-mentioned actions of lifting the vibrator, adding materials and punching the vibrator downward to compact the materials are repeated until the construction of the entire vibratory pile is completed.

[0003] During the construction of existing vibratory piles, an inclined chute is usually set directly under the hopper to allow the material to slide into the vibratory hole for vibratory compaction. The existing material adding method can usually only add material to one vibratory hole. However, during the construction of vibratory piles, it is usually necessary to construct multiple vibratory piles in batches to ensure that the entire building foundation is compacted and reinforced. Therefore, the current material adding method requires a feeding mechanism for each vibratory pile, otherwise the pile making efficiency is low, and setting up multiple feeding mechanisms will unnecessarily increase the construction cost. The existing flexible feeding method is to directly shovel the material through a bucket truck and then add the material to the vibratory hole. However, adding material through a bucket truck will cause the material to accumulate at the vibratory hole mouth, inducing problems such as collapse of the vibratory hole.

[0004] Based on the above background, the inventor has designed a multi-point displacement feeding device for vibratory pile construction to solve the above problems, and thus proposed the present application. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0047] like Figures 1 to 3 As shown, this embodiment provides a multi-point position-changing feeding device for vibratory pile construction, comprising:

[0048] A material unloading mechanism (1), a weighing and feeding mechanism (3), a lifting mechanism (5), a position changing mechanism (2) and a rotating mechanism (6), wherein:

[0049] One end of the weighing and feeding mechanism (3) is movably connected to the top of the lifting mechanism (5), and the other end is movably connected to the top of the rotating mechanism (6) and is located directly below the unloading port (121) of the unloading mechanism (1);

[0050] The bottom of the lifting mechanism (5) is arranged on the arc frame (21);

[0051] The transposition mechanism (2) comprises a horizontally arranged arc frame (21) and a transposition drive for driving the lifting mechanism (5) to move back and forth on the arc frame (21) along an arc line.

[0052] The concept of this embodiment is: by setting a feeding mechanism (1), a weighing and feeding mechanism (3), a lifting mechanism (5), a transposition mechanism (2) and a rotating mechanism (6), the feeding mechanism (1) with a heavier weight can be set away from the vibro-punched holes in the vibro-punched construction. At the same time, by using the transposition mechanism (2) and the rotating mechanism (6), the discharge end of the weighing and feeding mechanism (3) is rotated to the top of the vibro-punched holes at different positions, and the vibro-punched holes at multiple positions are fed, so as to realize the design concept of one hopper corresponding to multiple vibro-punched holes. This effectively solves the problem that the vibro-punched hole feeding method in the prior art can only be a single bucket for a single hole, or can only use a forklift to add materials, resulting in material accumulation at the hole mouth, which is easy to induce the collapse of the vibro-punched hole.

[0053] In addition, in a specific construction scenario, there is also the problem of uneven ground in the construction site. There may be a height difference between the specific location of the vibro-punched hole and the location of the unloading mechanism (1). Therefore, a lifting mechanism (5) is provided below the weighing and feeding mechanism (3) so that the height of the discharge end of the weighing and feeding mechanism (3) can be raised to the top of the vibro-punched hole, thereby solving the problem of inconvenience in feeding caused by the uneven construction site.

[0054] Furthermore, the weighing and feeding mechanism (3) of the present application also has a weighing function, so that the amount of material added is easier to control compared to the existing method of direct material feeding by a forklift or material feeding by a hopper chute.

[0055] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the transposition mechanism (2) further comprises a transposition chain (23) arranged on the arc-shaped outer side surface of the arc frame (21), and a transposition motor (24) arranged in an inverted manner at the bottom of the lifting mechanism (5);

[0056] The two ends of the transposition chain (23) are respectively fixed to the two ends of the arc frame (21);

[0057] The output shaft of the transposition motor (24) is provided with a transposition sprocket engaged with the transposition chain (23). Through the transposition motor (24), the transposition sprocket and the transposition chain (23), when the transposition motor (24) rotates forward or reversely, the lifting mechanism (5) can be driven to move along the arc on the arc frame (21), thereby realizing the transfer of the discharge end of the weighing and feeding mechanism (3) to different positions.

[0058] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the center angle of the arc corresponding to the arc of the arc frame (21) ranges from 30° to 120°. In this embodiment, the center angle of the arc corresponding to the arc of the arc frame (21) is 90°. The technicians can use other angles as needed, which will not be described in detail here.

[0059] The transposition mechanism (2) further comprises a connecting support frame (22);

[0060] The material discharge mechanism (1) comprises a hopper frame (11) and a discharge hopper (12); one end of a connecting support frame (22) is fixed on the hopper frame (11), and the other end is fixed on the inner side of the arc frame (21); the connecting support frame (22) is provided to ensure the stability of the arc frame (21).

[0061] In particular, in the present application, the hopper frame (11) is provided with four legs, and the connecting support frame is fixedly connected to two of the legs, thereby improving the stability of the arc frame (21) during the rotation of the lifting mechanism (5) and the weighing and feeding mechanism (3) after the transposition motor (24) is started.

[0062] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, a plurality of support plates (211) for supporting the transposition chain (23) are distributed on the arc-shaped outer wall of the arc frame (21), so as to prevent the transposition chain (23) from falling and contacting the ground at the construction site, thereby causing greater pollution to the transposition chain (23).

[0063] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the bottom of the lifting mechanism (5) is provided with a roller (7) located on an arc frame (21);

[0064] A rigid connecting frame (8) is also provided between the lifting mechanism (5) and the rotating mechanism (6). The roller (7) and the rigid connecting frame (8) are provided so that after the transposition motor (24) is started, the lifting mechanism (5) and the weighing and feeding mechanism (3) are in a rotating process, and the overall structure formed by the lifting mechanism (5), the rotating mechanism (6), and the weighing and feeding mechanism (3) has sufficient structural strength and stability.

[0065] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the rotating mechanism (6) comprises an upper plate (61) and a lower plate arranged in parallel, and a rotating shaft (63) arranged between the upper plate (61) and the lower plate;

[0066] It also includes a first hinge plate (41) and a second hinge plate (42) respectively fixed at two ends of the weighing and feeding mechanism (3);

[0067] The first hinge plate (41) and the second hinge plate (42) are hinged to the top of the upper plate (61) and the top of the lifting mechanism (5) respectively. By arranging the first hinge plate (41) and the second hinge plate (42), the weighing and feeding mechanism (3) can adapt to different inclination angles.

[0068] Specifically, in this embodiment, Figure 1 and Figure 2As shown, the first hinge plate (41) and the second hinge plate (42) have the same structure, both in the shape of an inverted triangle, and the bottoms of the inverted triangle first hinge plate (41) and the second hinge plate (42) are arc-shaped structures. The first hinge plate (41) and the second hinge plate (42) are both in the shape of an inverted triangle, and the bottoms are arc-shaped structures, so that part of the overall weight of the weighing and feeding mechanism (3) can be shared by the first hinge plate (41) and the second hinge plate (42), avoiding the entire weight of the weighing and feeding mechanism (3) from being pressed on the hinge shaft, thereby improving the overall stability.

[0069] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the lifting mechanism (5) comprises a lifting plate (51) arranged horizontally, and a plurality of lifting screw rods arranged vertically and spirally connected to the lifting plate (51);

[0070] Also included is a driving assembly for driving a plurality of lifting screws to rotate synchronously;

[0071] The driving assembly comprises a driving motor (53) and a transmission mechanism (54), wherein the transmission mechanism (54) comprises a driving gear and a plurality of driven gears, wherein the driven gears are distributed around the driving gear and mesh with the driving gear;

[0072] The driven gears are all installed at the bottom of the lifting screw and rotate synchronously with the lifting screw. In this embodiment, multiple driven gears are meshed with the driving gear, so that the multiple lifting screws rotate synchronously, thereby allowing the lifting plate (51) to rise or fall smoothly.

[0073] Specifically, in this embodiment, Figures 1 to 3 As shown, the weighing and feeding mechanism (3) comprises a conveying belt (32), a belt support frame (31), and a weighing component (34) and a speed measuring component (35) arranged on the belt support frame (31);

[0074] The belt support frame (31) is hinged on the top of the lifting mechanism (5), and the amount of material added to the vibrating hole can be calculated by setting a weighing component (34) and a speed measuring component (35).

[0075] Specifically, in this embodiment, Figure 3 As shown, a plurality of weighing components (34) are evenly distributed along the conveying direction of the conveying belt (32) and fixed on the belt support frame (31), and the weighing components (34) include a weighing bracket (341), a supporting roller (342) and a weighing sensor (343);

[0076] The weighing sensor (343) is arranged between the weighing bracket (341) and the belt support bracket (31), and the supporting roller (342) is located on the top of the weighing bracket (341) and is rotatably connected to the weighing bracket (341);

[0077] The speed measuring assembly (35) comprises a speed measuring bracket (351) fixedly connected to the belt support frame (31), and a test roller (7) rotatably connected to the free end of the speed measuring bracket (351), and the speed measuring roller (352) is pressed against the conveying belt (32). In this embodiment, the weighing sensor (343) is a pressure sensor, which is an existing device and is not described here.

[0078] By setting up a test bracket and a test roller (7), the conveying speed of the conveying belt (32) can be measured, and the material conveying amount can be obtained based on the weight data detected by the weighing sensor (343).

[0079] Specifically, in this embodiment, Figure 3 As shown, the number of the support rollers (342) is 3, and the 3 support rollers (342) are distributed in a U shape, so that the material supported on the conveyor belt (32) will collapse downward, which can prevent the material from sliding off the conveyor belt (32).

[0080] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
