Technical Field

[0001] This utility model relates to the field of building construction related technology, and in particular to a perforated pile driver with a positioning device. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into physical objects at designated locations. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site of construction work is called the "construction site" or "worksite." A pile driver consists of a pile hammer, pile frame, and auxiliary equipment. The pile hammer is attached to two parallel vertical guide rods at the front of the pile frame and is lifted by a hoisting hook. The pile frame is a steel tower structure with a winch at the rear for lifting the pile and pile hammer. Since pile drivers are needed in the construction process, a type of drilling pile driver with a positioning device is particularly required.

[0003] However, existing pile drivers used in construction are often lifted by a crane and then driven while suspended. This operation does not position the pile driver properly, which can easily cause the pile driver to deviate in the driving direction due to vibration during operation, thus affecting the efficiency of the pile driving operation. Utility Model Content

[0004] The purpose of this utility model is to provide a perforating pile driver with a positioning device to solve the problem mentioned in the background art that existing pile drivers used in building construction are often lifted by a crane during use and then driven in a suspended state. This operation does not position the pile driver, which easily leads to the pile driver deviating in the driving direction due to vibration during operation, thus affecting the efficiency of the pile driving operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a perforating pile driver with a positioning device, comprising a vibratory pile hammer, a pile driving column and a positioning mechanism, wherein the lower end of the vibratory pile hammer is connected to the pile driving column, the pile driving column vertically penetrates the center of the supporting base plate, four sets of positioning mechanisms are fixedly connected to the four corners of the supporting base plate, the upper end of each set of positioning mechanisms is connected to the supporting top plate, and the upper surface of the supporting top plate is provided with a clamping mechanism;

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a perforating pile driver with a positioning device, including a vibratory pile hammer 1, a pile driving column 2 and a positioning mechanism 4. The lower end of the vibratory pile hammer 1 is connected to the pile driving column 2, and the pile driving column 2 vertically penetrates the center of the supporting base plate 3. Four sets of positioning mechanisms 4 are fixedly connected to the four corners of the supporting base plate 3 respectively. The upper end of each set of positioning mechanisms 4 is connected to the supporting top plate 5, and the upper surface of the supporting top plate 5 is provided with a clamping mechanism 6.

[0022] The positioning mechanism 4 includes a fixing block 401, a damper 402, fixing bolts 403, and a shock-absorbing spring 405. The fixing block 401 is locked and fixed to the four corners of the support base plate 3 by the fixing bolts 403. The fixing block 401 has threaded holes 404 that match the fixing bolts 403. The damper 402 is vertically arranged and its two ends are fixedly connected to the support base plate 3 and the support top plate 5, respectively. The shock-absorbing spring 405 is coaxially sleeved on the outside of the damper 402, and its two ends are fixedly connected to the support base plate 3 and the support top plate 5, respectively. The positioning mechanism 4 consists of a fixing block 401, a damper 402, fixing bolts 403, threaded holes 403, and shock-absorbing spring 405. In setting 5, during use, after adjusting the vibratory pile hammer 1 and the pile driving column 2 to the working position, tighten the fixing bolt 403. At this time, the fixing bolt 403 passes through the threaded hole 404 through the fixing block 401. When the fixing bolt 403 is tightened into the ground, the fixing bolt 403 fixes the fixing block 401, thereby fixing the support base plate 3. Since one end of the pile driving column 2 passes through the support base plate 3, the support base plate 3 limits the position of the pile driving column 2. When the pile driver is working, the shock absorption spring 405 and the damper 402 cooperate to reduce the force of vibration on the support base plate 3, thereby preventing the pile driver from deviating in direction during operation.

[0023] Furthermore, the fixing block 401 is a metal block. The fixing blocks 401 in each group of positioning mechanisms 4 are symmetrically distributed at the two adjacent corners of the support base plate 3. The four groups of fixing blocks 401 fix the support base plate 3 to the ground by fixing bolts 403. With the setting of fixing blocks 401, the support base plate 3 can be fixed when the fixing blocks 401 are fixed by fixing bolts 403 during use.

[0024] Furthermore, there are four sets of shock-absorbing springs 405, each set of shock-absorbing springs 405 corresponding to a set of positioning mechanisms 4, and the extension and retraction direction of the shock-absorbing springs 405 is consistent with the axial direction of the damper 402. By setting the shock-absorbing springs 405, when used together with the damper 402, the shock-absorbing springs 405 can reduce the vibration generated by the pile driver on the supporting base plate 3 when it is in operation, thereby preventing the pile driver from shifting its position.

[0025] Furthermore, the clamping mechanism 6 includes two symmetrically arranged clamping components. Each clamping component includes a support block 601, a sleeve 602, a slide rod 603, and a clamping block 605. The support block 601 is fixed to the upper surface of the support top plate 5. The sleeve 602 is horizontally welded to the outside of the support block 601. The slide rod 603 is slidably inserted into the sleeve 602. An arc-shaped clamping block 605 is fixedly connected to the outer end of the slide rod 603. Through the arrangement of the support block 601, sleeve 602, slide rod 603, reinforcing spring 604, clamping block 605, protective plate 606, and handle 607, when in use, pulling the handle 607 will activate the handle. 607 drives the clamping block 605 to move towards the support block 601, the reinforcing spring 604 is compressed and deformed, and at the same time the slide rod 603 slides into the sleeve 602. After the piling column 2 passes through the support top plate 5, the force applied to the handle 607 is released. At this time, the reinforcing spring 604 is rebounded and deformed. The rebounded reinforcing spring 604 drives the clamping block 605 to return to its original position. At this time, the clamping blocks 605 of the two sets of arc blocks clamp and fix the piling column 2. At the same time, the protective plate 606 is set between the clamping block 605 and the piling column 2, so as to avoid the clamping block 605 from damaging the piling column 2.

[0026] Furthermore, a reinforcing spring 604 is fitted on the outer side of the sleeve 602. One end of the reinforcing spring 604 is welded to the support block 601, and the other end is welded to the clamping block 605. The elastic force direction of the reinforcing spring 604 is opposite to the sliding direction of the slide rod 603. With the setting of the reinforcing spring 604, when in use, the rebound deformation of the reinforcing spring 604 can drive the clamping block 605 to return to its original position so that the clamping block 605 clamps and fixes the piling column 2.

[0027] Furthermore, a rubber protective sheet 606 is bonded to the inner side of the clamping block 605, and a U-shaped handle 607 is welded to the outer side.

[0028] Furthermore, the curvature of the arc-shaped clamping block 605 matches the outer circumference of the pile pipe, and the openings of the two sets of clamping blocks 605 are arranged opposite each other to form a clamping space. With the clamping block 605 in use, since the clamping block 605 is an arc-shaped block, the clamping block 605 can fit tightly against the pile driving column 2, thereby stably clamping the pile driving column 2.

[0029] Furthermore, the center of the supporting top plate 5 has a through hole for the piling column 2 to pass through, and the inner wall of the through hole is fitted with a wear-resistant bushing.

[0030] Working principle: Pulling handle 607 causes clamping block 605 to move towards support block 601, compressing spring 604. Simultaneously, slide rod 603 slides into sleeve 602, driving the piling column 2 through the support top plate 5. Releasing the force on handle 607 causes spring 604 to rebound, returning clamping block 605 to its original position. At this point, the two sets of arc-shaped clamping blocks 605 clamp and fix the piling column 2. A protective plate 606 is positioned between clamping block 605 and piling column 2, preventing clamping block 605 from being clamped. 5. Damage to the pile driving column 2: After adjusting the vibratory pile hammer 1 and the pile driving column 2 to the working position, tighten the fixing bolt 403. At this time, the fixing bolt 403 passes through the fixing block 401 through the threaded hole 404. When the fixing bolt 403 is tightened into the ground, the fixing bolt 403 fixes the fixing block 401, thereby fixing the support base plate 3. Since one end of the pile driving column 2 passes through the support base plate 3, the support base plate 3 limits the position of the pile driving column 2. When the pile driver is working, the shock absorption spring 405 and the damper 402 cooperate to reduce the force of vibration on the support base plate 3, thereby preventing the pile driver from deviating in direction during operation.
