Description

Technical Field

[0001] The present application relates to the technical field of vibroflotation construction equipment, and in particular to a retaining device and vibroflotation construction equipment. Background Art

[0002] Vibroflotation is a method of foundation treatment. Generally, a vibrator with a guide rod is lifted by lifting equipment. Under the action of the vibrator, holes are vibrated in the foundation soil layer, and then backfilled with gravel and other fillers, and vibrated to form a reinforcement body, thereby achieving the foundation treatment purpose of improving the bearing capacity of the foundation.

[0003] In order to reduce the height of construction equipment and eliminate quality and safety hazards during construction, the existing vibratory impactor guide rods are mostly telescopic, with hanging points set on the innermost or outermost guide rods. The guide rods are generally connected to the mother machine through wire ropes. The extension of the guide rods is completed by their own gravity, and the retraction of the guide rods is completed by the lifting of the wire ropes. However, this setting method makes the extension and retraction sequence of the guide rods uncontrollable, which is not convenient for construction workers to complete the rigid connection or removal of adjacent guide rods, resulting in the vibratory impact effect being difficult to meet construction needs.

[0025] With respect to the above-mentioned background technology, the holding device provided in the embodiment of the present application is used for the telescopic guide rod of the vibrator, and the holding device includes a bracket, a holding assembly, a holding control assembly, a clamping assembly and a clamping control assembly. Among them, the bracket is used to connect with the device body, the holding assembly can be movably arranged on the bracket, the holding assembly is used to open and close relative to the bracket, and is used to form a holding cavity for the telescopic guide rod to pass through and be maintained at a preset construction position when closed, the holding control assembly is connected to the bracket and the holding assembly, the holding control assembly is used to control the movement of the holding assembly relative to the bracket to achieve the opening and closing of the holding assembly, the clamping assembly can be movably arranged on the bracket, the clamping assembly is used to clamp the guide rod body in the telescopic guide rod that is slidably connected to the guide rod body to be extended in accordance with the extension sequence set by the telescopic guide rod, so that the guide rod body to be extended is extended under the action of gravity, the clamping control assembly is connected to the bracket and the clamping assembly, and the clamping control assembly is used to control the movement of the clamping assembly relative to the bracket to clamp the guide rod body in the telescopic guide rod.

[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] It should be noted that the directional words such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.

[0049] Please refer to Figures 1 to 5 , Figure 1 This is a front view of the retaining device in the embodiment of the present application; Figure 2 for Figure 1 A schematic diagram of the holding device holding the assembly in a closed state; Figure 3 for Figure 1 A schematic diagram of the holding device showing the holding component in an open state; Figure 4 for Figure 1 A control block diagram of the holding device shown; Figure 5 Schematic diagram of the structure of the telescopic guide rod in the embodiment of the present application.

[0050] The retaining device provided in the embodiment of the present application is used to keep the telescopic guide rod 100 of the vibrator in a preset construction position so that the telescopic guide rod 100 can be extended according to a preset extension sequence. The retaining device includes a bracket 10, a retaining assembly 20, a retaining control assembly 30, a clamping assembly 40 and a clamping control assembly 50.

[0051] The bracket 10 is slidably connected to the device body, and the bracket 10 is used to support the holding component 20, the holding control component 30, the clamping component 40 and the clamping control component 50.

[0052] The retaining assembly 20 is movably disposed on the bracket 10 . The retaining assembly 20 is used to be opened and closed relative to the bracket 10 , and is used to form a retaining cavity for the telescopic guide rod 100 to pass through and be retained in a preset construction position when closed.

[0053] The holding control assembly 30 is connected to the bracket 10 and the holding assembly 20 . The holding control assembly 30 is used to control the movement of the holding assembly 20 relative to the bracket 10 to achieve the opening and closing of the holding assembly 20 .

[0054] The clamping assembly 40 is movably disposed on the bracket 10, and is used to clamp the guide rod body of the telescopic guide rod 100 that is slidably connected to the guide rod body to be extended according to the extension sequence set by the telescopic guide rod 100, so that the guide rod body to be extended is extended under the action of gravity.

[0055] The clamping control assembly 50 is connected to the bracket 10 and the clamping assembly 40 . The clamping control assembly 50 is used to control the movement of the clamping assembly 40 relative to the bracket 10 to clamp the guide rod body in the telescopic guide rod 100 .

[0056] On the one hand, the holding control component 30 controls the movement of the holding component 20 relative to the bracket 10 to realize the opening and closing of the holding component 20. When the holding component 20 is closed, a holding cavity can be formed for the telescopic guide rod 100 to pass through and be maintained at a preset construction position.

[0057] In this way, not only can the telescopic guide rod 100 be prevented from shaking when being installed to avoid danger, but the telescopic guide rod 100 can also be kept aligned with the construction hole in the foundation soil layer during the construction process to ensure construction accuracy.

[0058] On the other hand, the clamping control component 50 is used to control the movement of the clamping component 40 relative to the bracket 10 to clamp the guide rod body in the telescopic guide rod 100, so that the guide rod body to be extended in the telescopic guide rod 100 is extended according to the set extension sequence under the action of gravity. Taking the telescopic guide rod 100 including the first guide rod body 101, the second guide rod body 102 and the third guide rod body 103 as an example, the first guide rod body 101 is connected to the vibrator, and the first guide rod body 101 can perform telescopic movement relative to the second guide rod body 102, and the second guide rod body 102 can perform telescopic movement relative to the third guide rod body 103.

[0059] In this way, when the telescopic guide rod 100 in the retracted state needs to be extended, the second guide rod body 102 and the third guide rod body 103 are first clamped by the clamping assembly 40, so that the second guide rod body 102 and the third guide rod body 103 remain in a stationary state, and the first guide rod body 101 is controlled to extend relative to the second guide rod body 102. When the first guide rod body 101 is extended to the maximum stroke, the first guide rod body 101 and the second guide rod body 102 are connected. Then, the third guide rod body 103 is clamped by the clamping assembly 40, so that the third guide rod body 103 remains in a stationary state, and the second guide rod body 102 is controlled to extend relative to the third guide rod body 103. When the second guide rod body 102 is extended to the maximum stroke, the second guide rod body 102 and the third guide rod body 103 are connected. Finally, the first guide rod body 101, the second guide rod body 102 and the third guide rod body 103 are controlled to descend together for construction.

[0060] It should be noted that in order to better adapt to the principle of the vibration-injection method, it is often necessary to manually complete the rigid connection or dismantling work with the adjacent guide rod body after each section of the guide rod body completes the extension or retraction action. For example, after each section of the guide rod body completes the extension, it needs to be rigidly connected to the adjacent guide rod body. In this way, the telescopic guide rod 100 in the extended state can be connected into an integral structure to ensure the work efficiency and construction effect during the vibration-injection construction process.

[0061] Compared with the traditional setting method of uncontrollable telescopic sequence, it is not convenient for construction workers to complete the rigid connection between adjacent guide rods, resulting in the vibration effect being difficult to meet the construction requirements. The retaining device in the present application can control the telescopic guide rod 100 to extend in the set extension sequence, which is convenient for construction workers to seal and rigidly connect the sections of the telescopic guide rod 100. It can not only better adapt to the basic principle of the vibration method and improve the vibration construction effect, but also, during the construction process, the sealing and rigid connection operations between the sections of the telescopic guide rod 100 are all performed on the ground, which is convenient to operate and safe to operate. Therefore, while ensuring the quality of the vibrating crushed stone pile body, there is no need to configure additional auxiliary equipment, which reduces costs and improves construction efficiency.

[0062] In some embodiments, the clamping assembly 40 includes two clamping bodies, both of which are rotatably connected to the bracket 10, and the rotation axes of the two clamping bodies are parallel to each other. The two clamping bodies are used to rotate relative to the bracket 10 to clamp the telescopic guide rod 100 when closed and release the telescopic guide rod 100 when opened.

[0063] In this embodiment, the two clamping bodies are rotatably connected to the bracket 10 through the main pin shaft 60. The two main pin shafts 60 are arranged on the bracket 10 at intervals. The two clamping bodies rotate in a circular direction around the axis of the corresponding main pin shaft 60 to achieve opening and closing.

[0064] Furthermore, the clamping control assembly 50 includes two clamping driving members, one end of which is hinged to the bracket 10 and the other end is hinged to the corresponding clamping body. The clamping driving member is used to drive the corresponding clamping body to rotate relative to the bracket 10.

[0065] The clamping drive component is specifically a clamping cylinder, one end of which is hinged to the bracket 10, and the other end is hinged to the outer wall of the corresponding clamping body. In this way, through the telescopic movement of the two clamping cylinders, the two clamping bodies are controlled to rotate relative to the bracket 10 to achieve the opening and closing of the two clamping bodies.

[0066] In some embodiments, the two clamping bodies may also be slidably connected to the bracket 10. The two clamping bodies may be opened and closed by sliding relative to the bracket 10, thereby clamping the telescopic guide rod 100 when the two clamping bodies are closed.

[0067] In this paper, it is preferred to use two clamping bodies in a rotational arrangement.

[0068] In order to ensure that the two clamping bodies clamp the telescopic guide rod 100, the inner walls of the two clamping bodies are provided with protrusions, which are used to engage with the grooves on the outer surface of the telescopic guide rod 100 to increase the force between the clamping bodies and the telescopic guide rod 100, thereby ensuring that the two clamping bodies clamp the telescopic guide rod 100.

[0069] In some embodiments, the number of clamping assemblies 40 and clamping control assemblies 50 is at least two, and any two adjacent clamping assemblies 40 are arranged on the bracket 10 at a preset interval in the vertical direction. At least two clamping assemblies 40 are used to clamp the guide rod body in the telescopic guide rod 100 that is slidably connected to the guide rod body to be extended according to the extension sequence set by the telescopic guide rod 100.

[0070] Taking the telescopic guide rod 100 including the first guide rod body 101, the second guide rod body 102 and the third guide rod body 103 as an example, the diameters of the first guide rod body 101, the second guide rod body 102 and the third guide rod body 103 are increased in sequence, the upper end of the first guide rod body 101 is connected to the steel wire rope of the construction equipment, and the lower end is connected to the vibrator, the first guide rod body 101 is used as the inner conduit of the second guide rod body 102, and can perform telescopic movement relative to the second guide rod body 102, and the second guide rod body 102 is used as the inner conduit of the third guide rod body 103, and can perform telescopic movement relative to the third guide rod body 103. The guide rod bodies can slide between each other through the cooperation of the key and the keyway, thereby realizing the telescopic movement of the corresponding guide rod body.

[0071] Correspondingly, the number of the clamping assemblies 40 and the number of the clamping control assemblies 50 are both two, and the two clamping assemblies 40 are arranged on the bracket 10 at a preset interval in the vertical direction.

[0072] The two clamping bodies of any clamping assembly 40 are both arranged as semicircular structures, and the clamping bodies of the two semicircular structures can form a cavity structure close to a full circle after being closed, wherein the diameter of the cavity structure formed by the two clamping bodies of the upper clamping assembly 40 is slightly smaller than the diameter of the third guide rod body 103 in the telescopic guide rod 100, and a general value is 10-20 mm, so that the stability of the clamping of the third guide rod body 103 in the telescopic guide rod 100 by the upper clamping assembly 40 can be ensured; the diameter of the cavity structure formed by the two clamping bodies of the lower clamping assembly 40 is slightly smaller than the diameter of the second guide rod body 102 in the telescopic guide rod 100, and a general value is 10-20 mm, so that the stability of the clamping of the second guide rod body 102 in the telescopic guide rod 100 by the lower clamping assembly 40 can be ensured.

[0073] In some embodiments, the holding assembly 20 includes two holding bodies 21, and the holding control assembly 30 includes two holding driving members 31. Both holding bodies 21 are rotatably connected to the bracket 10. The rotation axes of the two holding bodies 21 are parallel to each other. The two holding bodies 21 are used to rotate relative to the bracket 10 to achieve opening and closing. One end of the holding driving member 31 is hinged to the bracket 10, and the other end is hinged to the corresponding holding body 21. The holding driving member 31 is used to drive the corresponding holding body 21 to rotate relative to the bracket 10. Among them, the two holding bodies 21 are configured to form a holding cavity when closed, and the holding cavity is used to limit the displacement of the telescopic guide rod 100 in the horizontal direction and to allow the telescopic guide rod 100 to move in the vertical direction.

[0074] Similarly, the two retaining bodies 21 are both configured as semicircular structures. When the two semicircular retaining bodies 21 are closed, a cavity structure close to a full circle can be formed, namely a retaining cavity. The diameter of the retaining cavity is slightly larger than the diameter of the third guide rod body 103 in the telescopic guide rod 100, and a general value is 10-20 mm. In this way, the telescopic guide rod 100 can shuttle up and down in the retaining cavity. The retaining cavity is used to limit the displacement of the telescopic guide rod 100 in the horizontal direction and to allow the telescopic guide rod 100 to move in the vertical direction.

[0075] Similarly, the retaining driving member 31 is specifically a retaining cylinder, one end of which is hinged to the bracket 10, and the other end is hinged to the outer wall of the corresponding retaining body 21. In this way, through the telescopic movement of the two retaining cylinders, the two retaining bodies 21 are controlled to rotate relative to the bracket 10 to realize the opening and closing of the two retaining bodies 21.

[0076] In this way, the oil cylinder controls the opening and closing of the corresponding holding body 21. After the two holding bodies 21 are closed, the telescopic guide rod 100 can pass through the cavity structure in the middle. Since the diameter of the circle formed after the closure is slightly larger than the maximum diameter of the telescopic guide rod 100, the telescopic guide rod 100 can move up and down therein, and will not move significantly in the horizontal direction, thereby ensuring the construction accuracy. After the upper clamping assembly 40 is closed, its size is slightly smaller than the third guide rod body 103, and it will tightly hold the third guide rod body 103. At this time, the weight of the third guide rod body 103 acts on the upper clamping assembly 40, and when the second guide rod body 102 is telescoped, the third guide rod body 103 is ensured to be in a stationary state. When the upper clamping assembly 40 is in an open state, the third guide rod body 103 can move along the guide rod axis direction. After the clamping assembly 40 below is closed, its size is slightly smaller than the second guide rod body 102, and it will tightly hold the second guide rod body 102. At this time, the weight of the second guide rod body 102 acts on the clamping assembly 40 below, and when the first guide rod body 101 is extended or retracted, the second guide rod body 102 is ensured to be in a stationary state. When the clamping assembly 40 below is in an open state, the second guide rod body 102 can move along the guide rod axis direction.

[0077] When the telescopic guide rod 100 in the retracted state needs to be extended, the position of the telescopic guide rod 100 or the holding device is adjusted, and the two holding bodies 21 of the holding assembly 20 are closed. At this time, the telescopic guide rod 100 passes through the middle holding cavity of the two holding bodies 21. First, the second guide rod body 102 and the third guide rod body 103 are clamped by the two clamping assemblies 40 respectively, so that the second guide rod body 102 and the third guide rod body 103 remain in a stationary state, and the first guide rod body 101 is lowered by the wire rope between the construction equipment. At this time, under the action of gravity, the first guide rod body 101 begins to descend, that is, the first guide rod body 101 extends relative to the second guide rod body 102. The clamping assembly 40 clamps the second guide rod body 102 and the third guide rod body 103 respectively, so that the second guide rod body 102 and the third guide rod body 103 remain stationary, and only the first guide rod body 101 is in motion. When the first guide rod body 101 is extended to the maximum stroke, the wire rope between the first guide rod body 101 and the construction equipment is stopped, and the construction personnel connect the first guide rod body 101 and the second guide rod body 102 to form a whole. Since the holding device is located above the ground, the position where the construction needs to be connected can also be controlled above the ground plane, which is convenient for the construction personnel to operate. After the operation is completed, the clamping assembly 40 below is released. At this time, due to the second guide rod body 101, the second guide rod body 102 is The rod body 102 is connected to the first guide rod body 101 as a whole, and the first guide rod body 101 is subjected to the upward pulling force of the wire rope, so the second guide rod body 102 will not move downward due to its gravity, and the wire rope between the first guide rod body 101 and the construction equipment will continue to be lowered. At this time, since the third guide rod body 103 is clamped by the clamping assembly 40 above, the third guide rod body 103 is in a stationary state. Under the action of gravity, the first guide rod body 101 and the second guide rod body 102 descend together, that is, the second guide rod body 102 extends relative to the third guide rod body 103. When the second guide rod body 102 is extended to the maximum stroke, the lowering of the first guide rod body 101 and the construction equipment is stopped. The construction personnel can connect the second guide rod body 102 and the third guide rod body 103 with the steel wire rope in the preparation room to form the two into a whole. After the operation is completed, the upper clamping assembly 40 is released. At this time, since the second guide rod body 102 and the third guide rod body 103 are connected as a whole, and the first guide rod body 101 is subjected to the upward pulling force of the steel wire rope, the third guide rod body 103 will not move downward due to its gravity. The steel wire rope between the first guide rod body 101 and the construction equipment is continued to be lowered. Under the action of gravity, the first guide rod body 101, the second guide rod body 102 and the third guide rod body 103 descend together. At this time, the extension process of the entire telescopic guide rod 100 is completed.

[0078] When the telescopic guide rod 100 in the extended state needs to be retracted, the wire rope between the first guide rod body 101 and the construction equipment is lifted, and the whole composed of the first guide rod body 101, the second guide rod body 102 and the third guide rod body 103 moves upward under the tension of the steel wire. When it moves to a predetermined height, the wire rope between the first guide rod body 101 and the construction equipment is stopped, and the upper clamping assembly 40 is closed to make it tightly hold the third guide rod body 103. The construction personnel remove the connecting device between the second guide rod body 102 and the third guide rod body 103. Since the gravity of the third guide rod body 103 acts on the upper clamping assembly 40, the third guide rod body 103 will not move downward, and the wire rope between the first guide rod body 101 and the construction equipment is lifted, and the second guide rod body 102 and the third guide rod body 103 are closed. The whole formed by the rod body 102 and the first guide rod body 101 moves upward under the tension of the steel wire. When the second guide rod body 102 is completely retracted into the third guide rod body 103, the lifting of the steel wire rope between the first guide rod body 101 and the construction equipment is stopped, and the clamping assembly 40 below is closed to tightly hold the second guide rod body 102. The construction personnel remove the connecting device between the second guide rod body 102 and the first guide rod body 101. Since the gravity of the second guide rod body 102 acts on the clamping assembly 40 below, the second guide rod body 102 will not move downward, and continue to lift the steel wire rope between the first guide rod body 101 and the construction equipment until the first guide rod body 101 is completely retracted into the second guide rod body 102. At this time, the retraction of the guide rod is completed.

[0079] It should be noted that the telescopic guide rod 100 selected in this embodiment is the innermost rod connected to the construction host through a steel wire rope, that is, the telescopic sequence is from the inside to the outside, and the same applies to the telescopic guide rod 100 being the outermost rod connected to the construction host through a steel wire rope, and the telescopic sequence is from the outside to the inside. In addition, this embodiment is described by taking a three-section telescopic guide rod 100 as an example. If the number of sections of the telescopic guide rod 100 is increased or decreased, it is only necessary to increase or decrease the corresponding clamping components 40.

[0080] In some embodiments, the number of clamping assemblies 40 may also be one. In this case, the retaining device also includes a reducing jacket, which is installed inside the clamping assembly 40. The reducing jacket includes a plurality of jacket bodies. Any two adjacent jacket bodies are detachably connected. The outer diameters of the jacket bodies are different, and the structure of the jacket body is used to adapt to the corresponding guide rod body in the telescopic guide rod 100.

[0081] Specifically, according to the arrangement mode in which the telescopic guide rod 100 includes the first guide rod body 101, the second guide rod body 102 and the third guide rod body 103, the reducing jacket includes the first jacket body and the second jacket body, the first jacket body and the second jacket body are respectively adapted to the second guide rod body 102 and the third guide rod body 103, the first jacket body and the second jacket body are detachably connected, and when it is necessary to clamp the second guide rod body 102 and the third guide rod body 103, the second guide rod body 102 and the third guide rod body 103 are clamped respectively by the first jacket body and the second jacket body, so that the first guide rod body 101 extends relative to the second guide rod body 102, and after the first guide rod body 101 is fully extended, the first jacket body is disassembled, and at this time, the third guide rod body 103 is clamped only by the second jacket body, so that the second guide rod body 102 extends relative to the third guide rod body 103.

[0082] In this embodiment, by providing a clamping assembly 40 and configuring a reducing sleeve, compared with the method of providing two clamping assemblies 40 , the structure of the holding device can be simplified and the weight of the holding device can be reduced.

[0083] In order to facilitate the sliding connection between the bracket 10 and the equipment body, a sliding connection structure 11 is provided on the outer wall of the bracket 10, and the sliding connection structure 11 is used for sliding connection between the holding device and construction equipment such as drilling rigs and pile frames. The sliding connection structure 11 is specifically a mounting block or a guide block, and the mounting block or the guide block is used to be slidably connected with the guide track of the equipment body, so that the bracket 10 slides relative to the equipment body in the vertical direction, so as to achieve the purpose of adjusting the position of the holding device in the vertical direction.

[0084] To this end, a pulley assembly 12 is also provided on the bracket 10, and the pulley assembly 12 is used for adjusting the winding of the rope. The bracket 10 is hoisted by adjusting the rope so that the holding device can adjust its position in the vertical direction to facilitate subsequent vibro-impact construction in the foundation soil layer.

[0085] Specifically, the pulley assembly 12 includes a pulley frame arranged at the upper end of the bracket 10 and a pulley body rotatably arranged in the pulley frame. The pulley body is connected to the pulley frame through a pin shaft. The adjusting cable can be a steel wire rope. The steel wire rope passes around the pulley body and is connected to the winch of the vibratory construction equipment. The height of the retaining device can be adjusted through the steel wire rope.

[0086] In some embodiments, the holding device further includes a position detection component 70, a state detection component 80 and a control module 90. The position detection component 70 is used to detect the position of the telescopic guide rod 100, the state detection component 80 is used to detect the working state of the telescopic guide rod 100, the control module 90 is connected to the position detection component 70, the state detection component 80, the holding control component 30 and the clamping control component 50 for communication, and the control module 90 is used to control the holding control component 30 and the clamping control component 50 to operate according to the position of the telescopic guide rod 100 detected by the position detection component 70 and the working state of the telescopic guide rod 100 detected by the state detection component 80.

[0087] It can be seen that the current position of the telescopic guide rod 100 is detected by the position detection component 70, and the hoisting equipment for hoisting the telescopic guide rod 100 is controlled by the control module 90, so that the telescopic guide rod 100 is adjusted to a preset construction position, such as the position directly above the vibrating hole. The position detection component 70 can be a position sensor or an encoder for providing accurate position feedback; the state detection component 80 is used to monitor the working state of the telescopic guide rod 100, such as whether the telescopic guide rod 100 is moving, whether it has reached a predetermined position, whether it encounters an obstacle, etc., especially when the first guide rod body 101 is extended, it is necessary to detect the extension state of the first guide rod body 101, and automatically control the next operation after the first guide rod body 101 is fully extended; the control module 90, as the brain, is responsible for receiving information from the position detection component 70 and the state detection component 80, and controls the actions of the holding control component 30 and the clamping control component 50 according to this information. The control module 90 is specifically a microcontroller, a PLC (programmable logic controller) or other types of controllers.

[0088] By adopting the above-mentioned arrangement, the telescopic guide rod 100 can be automatically controlled to extend and retract according to the set telescopic sequence, thereby realizing automated operation, which can reduce the workload of construction workers and reduce labor costs.
