Description

Technical Field

[0001] The present application relates to the technical field of pile hole construction, and in particular to a hanger for cast-in-place piles. Background Art

[0002] A cast-in-place pile is a type of pile constructed by creating a hole in place and then pouring concrete or concrete. Common methods include bored cast-in-place piles and sunken pipe cast-in-place piles. When constructing in mountainous areas, due to geographical factors, large drilling equipment is not easily accessible. Therefore, manual excavation is often used for cast-in-place pile construction. Currently, manual excavation of cast-in-place piles requires a hoist to promptly remove the excavated soil to facilitate further excavation.

[0003] The commonly used lifting tools at present include a hanger, a winch and a slag bucket, wherein the hanger is fixedly installed just above the bored pile, the winch is fixedly installed on the hanger, the slag bucket is connected to the winch by a rope, and the winch drives the slag bucket to move vertically in the bored pile; when in use, the manually excavated soil is placed in the slag bucket, the winch is started, and the slag bucket is lifted to the ground, the soil in the slag bucket is manually dumped out, and then the dumped slag bucket is placed in the bored pile, so as to circulate and discharge the soil in the bored pile.

[0004] However, since the location where the slag bucket is dumped into the soil is as far away from the bored pile as possible, and the slag bucket is located at the center of the bored pile, it is necessary to manually pull the slag bucket horizontally for a distance to dump the soil in the slag bucket, which greatly increases the workload of workers dumping the soil and reduces the efficiency of soil transportation. Utility Model Content

[0005] In order to reduce the workload of workers dumping soil and improve the efficiency of soil transportation, the present application provides a hanger for cast-in-place piles.

[0006] The present application provides a hanger for bored piles, which adopts the following technical solution:

[0007] A hanger for bored piles, comprising a support frame, a track beam, a lifting assembly, and a drive assembly. The support frame is arranged on the ground and directly above the bored piles, the track beam is arranged on the support frame and extends out of the support frame, the lifting assembly is slidably arranged on the track beam and is used to lift the soil in the bored piles out of the bored piles, and the drive assembly is arranged on the support frame and is used to drive the lifting assembly to slide and transport the soil lifted out of the bored piles to the outside of the support frame for dumping.

[0008] By adopting the above technical solution, the lifting assembly lifts the soil in the bored pile to the designated position, and then the driving assembly drives the lifting assembly to slide out of the support frame along the track beam. When the lifting assembly moves to the dumping point, the soil in the lifting assembly is manually dumped out. After the dumping is completed, the driving assembly drives the lifting assembly to slide just above the bored pile, and then the soil in the bored pile is lifted again, so as to transport the soil in the bored pile out and dump it at the designated position, reduce the workload of workers dumping the soil, and improve the efficiency of soil transportation.

[0009] Furthermore, the track beam is an I-beam, and the drive assembly includes:

[0010] A clamping block, which is clamped on both sides of the track beam and can slide along the axis of the track beam, and the lifting assembly is arranged on the clamping block;

[0011] Rollers, multiple sets of rollers are rotatably mounted on the clamping blocks and in rolling contact with the track beams;

[0012] A driving motor is provided on the clamping block and is used to drive the plurality of roller groups to rotate.

[0013] By adopting the above technical solution, the driving motor drives the roller to rotate, thereby causing the clamping block to slide along the axis direction of the track beam, thereby driving the lifting assembly to slide on the track beam.

[0014] Furthermore, the support frame includes:

[0015] Columns, four groups of columns are set on the ground, and the four groups of columns are respectively located at the four corners of the rectangle;

[0016] A top frame, wherein the top frame is arranged on four groups of columns, and the track beam is arranged on the top frame and located in the middle of the top frame;

[0017] A cross bar, which is arranged on the top frame and connected to the track beam, and the cross bar and the track beam are perpendicular to each other;

[0018] Auxiliary support rods, multiple groups of the auxiliary support rods are arranged between adjacent columns and between the columns and the top frame support and are used to enhance the overall support strength. The multiple groups of the auxiliary support rods do not affect the sliding of the lifting assembly.

[0019] By adopting the above technical solution, four groups of columns support and fix the four corners of the top frame, and the cross bars assist the top frame to support and fix the track beam. At the same time, multiple groups of auxiliary support rods cooperate with each other to enhance the support strength between adjacent columns and between the columns and the top frame support, so as to facilitate the joint action of the lifting assembly, track beam and driving assembly to stably transport the soil in the cast-in-place pile.

[0020] Furthermore, a counterweight is provided on the opposite side of the support frame extending away from the track beam, and the bottom of the counterweight is in contact with the ground and is used to prevent the support frame from tilting over.

[0021] By adopting the above technical solution, the counterweight is used to increase the deadweight of the support frame on the opposite side of the support frame away from the track beam, thereby reducing the probability of the support frame tipping over when the lifting assembly is away from the track beam.

[0022] Furthermore, the counterweight comprises:

[0023] An installation frame, the installation frame is arranged on the support frame and abuts against the ground;

[0024] The counterweight block is placed in the installation frame and has a large deadweight.

[0025] By adopting the above technical solution, during installation, the installation frame is installed on the support frame, and then the configuration block is placed in the installation frame to form a counterweight.

[0026] Furthermore, a positioning rod inserted into the ground is slidably provided in the installation frame, the end of the positioning rod close to the ground is a conical structure, and the end of the positioning rod away from the ground is provided with a fixing head for increasing the contact area with the installation frame.

[0027] By adopting the above technical solution, when the installation frame is installed, the positioning rod is first inserted into the ground through the installation frame, thereby increasing the force exerted by the ground on the installation frame and reducing the demand for counterweight blocks.

[0028] Furthermore, the bottom of the support frame is arranged on the ground through a support plate, and an extension plate for increasing the contact area with the ground is arranged on the support plate on the side of the support frame away from the counterweight.

[0029] By adopting the above technical solution, the support plate increases the contact area between the column and the ground, and improves the supporting force of the ground on the support frame. At the same time, since the side of the support frame away from the counterweight exerts a greater force on the ground, the extension plate and the support plate cooperate with each other to reduce the pressure of the support frame on the ground, thereby reducing the probability of collapse due to excessive pressure on the ground in contact with the support frame.

[0030] Furthermore, limit blocks are provided on both ends of the track beam, and the limit blocks are used to prevent the lifting assembly from sliding out of the track beam.

[0031] By adopting the above technical solution, the limit block limits the reciprocating clamping block, reducing the probability of the clamping block driving the lifting assembly to slide out of the track beam.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. The slag bucket is driven to move up to the designated position by the winch, and then the driving motor drives the winch and the slag bucket to slide along the track beam out of the support frame. When the slag bucket moves to the dumping point, the soil in the slag bucket is dumped out manually. After the dumping is completed, the driving motor drives the winch and the slag bucket to slide just above the cast-in-place pile. The winch puts the empty slag bucket into the cast-in-place pile, so as to transport the soil in the cast-in-place pile out and dump it at the designated position, reducing the workload of workers dumping the soil and improving the efficiency of soil transportation.

[0034] 2. When the lifting assembly is located in the support frame, the counterweight is used to enhance the stability of the support frame. When the lifting assembly moves along the track beam to the end away from the support frame, the counterweight increases the deadweight of the side of the support frame away from the track beam, thereby reducing the probability of the support frame tipping over when the lifting assembly moves to the end away from the support frame.

[0038] The following is combined with Figure 1-2 This application is described in further detail.

[0039] The embodiment of the present application discloses a hanger for a bored pile.

[0040] Reference Figure 1 A hanger for bored piles includes a support frame 1, a track beam 2, a lifting assembly 3, and a driving assembly 4. The support frame 1 is set on the ground and is located directly above the bored pile. The track beam 2 is set on the support frame 1 and extends out of the support frame 1. The lifting assembly 3 is slidably set on the track beam 2 and is used to lift the soil in the bored pile out of the bored pile. The driving assembly 4 is set on the support frame 1 and is used to drive the lifting assembly 3 to slide and transport the soil lifted out of the bored pile to the outside of the support frame 1 for dumping.

[0041] Reference Figure 1The support frame 1 includes columns 11, a top frame 12, a cross bar 13 and an auxiliary support bar 14. There are four groups of columns 11. The four groups of columns 11 are fixedly installed on the ground in the vertical direction. The four groups of columns 11 are respectively located at the four corners of the rectangle; the top frame 12 is a rectangular structure composed of four groups of I-beams connected end to end. The four groups of columns 11 are respectively located at the four corners of the top frame 12; the cross bar 13 is fixedly installed on the top frame 12, the cross bar 13 and the track beam 2 are perpendicular to each other, and the track beam 2 is located in the middle of the cross bar 13; multiple groups of auxiliary support bars 14 are divided into cross bars according to the installation position 141, diagonal bracing rods 142 and reinforcing rods 143, wherein the transverse rod 141 is parallel to the plane of the top frame 12 and is used to connect two adjacent groups of columns 11, the transverse rod 141 is located on the side of the column 11 close to the ground, multiple groups of diagonal bracing rods 142 are staggered with each other and staggered to connect two adjacent columns 11, the diagonal bracing rods 142 are located on the side that is parallel to the track beam 2, and the reinforcing rods 143 are located on the side that intersects with the track beam 2. The reinforcing rods 143 are fixedly installed on the columns and diagonally support the top frame 12 close to the track beam 2, thereby reducing the probability of deformation of the top frame 12.

[0042] Reference Figure 1 The track beam 2 is fixedly mounted on the lower surface of the top frame 12 of the support frame 1. The track beam 2 is an I-beam. One end of the track beam 2 extends out of the support frame 1. The driving assembly 4 includes a clamping block 41, a roller 42 and a driving motor 43. The clamping block 41 is clamped on both sides of the track, and the clamping block 41 can slide along the axis direction of the track beam 2; there are multiple groups of rollers 42, and multiple groups of rollers 42 are rotatably mounted on the clamping block 41 and in rolling contact with the track beam 2, so as to facilitate the clamping block 41 to slide along the track beam 2; the driving motor 43 is fixedly mounted on the clamping block 41, and the driving motor 43 is arranged on the clamping block 41. The driving motor 43 is used to drive the multiple groups of rollers 42 to rotate, so as to drive the clamping block 41 to slide on the track beam 2.

[0043] Reference Figure 1 The lifting assembly 3 includes a winch 31 and a slag bucket 32. The winch 31 is fixedly mounted on the clamping block 41. The slag bucket 32 is connected to the winch 31 through a rope. The winch 31 can drive the slag bucket 32 to slide in the vertical direction, so as to facilitate the transportation of the soil in the cast-in-place pile out of the cast-in-place pile through the slag bucket 32.

[0044] Reference Figure 1After the slag bucket 32 is dumped, the driving motor 43 drives the hoist 31 and the slag bucket 32 to slide and return to the top of the cast-in-place pile, and then the hoist 31 drives the empty slag bucket 32 to descend into the cast-in-place pile, so as to facilitate the transportation of the soil.

[0045] Reference Figure 1 Since the clamping block 41 drives the winch 31 to move back and forth, in order to reduce the probability of the clamping block 41 sliding out of the track beam 2, limit blocks 21 are provided on both ends of the track beam 2. When the driving motor 43 drives the clamping block 41 to press against the limit block 21, the limit block 21 prevents the clamping block 41 from continuing to slide the track beam 2, thereby reducing the probability of the clamping block 41 driving the winch 31 to slide out of the track beam 2.

[0046] Reference Figure 1 When the winch 31 and the slag bucket 32 with soil move to the end of the track beam 2 away from the support frame 1, due to the deadweight of the winch 31, the slag bucket 32 and the soil, it is easy to make the pressure on the side of the support frame 1 close to the track beam 2 much greater than the pressure on the side of the support frame 1 away from the track beam 2, which can easily cause the support frame 1 to tip over. In order to reduce the probability of the support frame 1 tipping over, a counterweight 5 is provided on the opposite side of the support frame 1 away from the track beam 2. The bottom of the counterweight 5 is in contact with the ground. The counterweight 5 increases the deadweight of the side of the support frame 1 away from the track beam 2, thereby reducing the probability of the support frame 1 tipping over.

[0047] Reference Figure 1 and Figure 2 The counterweight 5 includes a mounting frame 51 and a counterweight block. The mounting frame 51 is a frame-shaped structure with an open top. The mounting frame 51 is fixedly mounted on the side wall of the support frame 1, and the bottom of the mounting frame 51 is pressed against the ground. The counterweight block is placed in the mounting frame 51, and the counterweight block has a large deadweight. The configuration block of this embodiment can be an object with a large deadweight, such as a steel block, a stone block, or a stacked earth block.

[0048] Reference Figure 1 and Figure 2A positioning rod 52 for inserting into the ground is slidably installed on the bottom of the mounting frame 51. The positioning rod 52 is convenient for ensuring that the force between the mounting frame 51 and the ground is increased, thereby reducing the weight requirement of the required configuration block, and also improving the stability of the support frame 1; the positioning rod 52 is a conical structure at one end close to the ground, so as to facilitate the insertion of the positioning rod 52 into the ground, and at the same time, the positioning rod 52 is fixedly installed at the end away from the ground with a fixed head for increasing the contact with the mounting frame 51; when in use, the mounting frame 51 is fixedly installed on the support frame 1, and then the positioning rod 52 is inserted into the ground, and finally the counterweight block is placed in the mounting frame 51. The counterweight block reduces the probability of the positioning rod 52 sliding out of the ground.

[0049] Reference Figure 1 In order to increase the supporting force of the ground on the support frame 1, the support frame 1 is placed on the ground through the support plate 6. Since the side of the support frame 1 away from the counterweight 5 exerts a greater force on the ground, in order to reduce the pressure of the support frame 1 on the ground, an extension plate 61 for increasing the contact area with the ground is fixedly installed on the support plate 6 on the side of the support frame 1 away from the counterweight 5. The bottom of the extension plate 61 is flush with the bottom of the support plate 6. The extension plate 61 cooperates with the support plate 6 to reduce the probability of collapse due to excessive pressure on the ground when in contact with the support frame 1.

[0050] The working principle of the embodiment of this application is as follows:

[0051] The slag bucket 32 is driven by the winch 31 to move up to the designated position, and then the driving motor 43 drives the winch 31 and the slag bucket 32 to slide out of the support frame 1 along the track beam 2. When the slag bucket 32 moves to the dumping point, the soil in the slag bucket 32 is dumped out manually. After the dumping is completed, the driving motor 43 drives the winch 31 and the slag bucket 32 to slide just above the cast-in-place pile, and the winch 31 puts the empty slag bucket 32 into the cast-in-place pile, so as to transport the soil in the cast-in-place pile out and dump it at the designated position, reduce the workload of workers dumping the soil, and improve the efficiency of soil transportation.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
