Description

Technical Field

[0001] This application relates to the field of steel sheet pile guiding frames, and in particular to a guiding frame for steel sheet pile construction. Background Art

[0002] A steel sheet pile is a profiled steel with a locking groove at the edge, which is divided into straight plate type, groove type and other shapes. The steel sheet pile can form cofferdams with different shapes as needed. By setting the steel sheet pile on one side of the inner wall of the foundation pit, it can protect the construction workers at the bottom of the pit and reduce the accident losses caused by the collapse of the foundation pit.

[0003] The related steel sheet pile guiding frame includes a bottom frame and fixing bolts. The bottom frame is a frame structure, and the fixing bolts are used to fix the bottom frame on one side of the foundation pit opening. The user hoists the steel sheet pile so that the steel sheet pile is vertically inserted into the foundation pit, thereby reducing the probability of the steel sheet pile swinging during hoisting and facilitating the accurate installation of the steel sheet pile by the construction workers.

[0004] The above-mentioned related technical solutions have the following defects: when the steel sheet pile is inserted into the bottom frame, there is a probability that the steel sheet pile will tilt in the bottom frame, which will cause the position of the steel sheet pile entering the foundation pit to shift, resulting in a poor positioning effect of the guiding frame on the steel sheet pile. Utility Model Content

[0005] In order to improve the positioning effect on the steel sheet pile, this application provides a guiding frame for steel sheet pile construction.

[0006] The guiding frame for steel sheet pile construction provided by this application adopts the following technical solutions:

[0007] A guiding frame for steel sheet pile construction includes a bottom frame, an upper top frame, a fixing mechanism and a supporting mechanism. The bottom frame is connected to the fixing mechanism, and the fixing mechanism is used to fix the bottom frame on the ground. The upper top frame is arranged above the bottom frame, and the supporting mechanism is connected to the upper top frame. The supporting mechanism is used to be fixed on the ground and support the upper top frame. Both the bottom frame and the upper top frame are arranged as frame structures.

[0008] By adopting the above technical solutions, by arranging the upper top frame above the bottom frame, there is a gap between the upper top frame and the bottom frame. When the steel sheet pile is inserted into both the bottom frame and the upper top frame at the same time, the bottom frame and the upper top frame limit the steel sheet pile at the same time, thereby reducing the probability of the steel sheet pile shaking or deflecting during hoisting, and improving the positioning effect of the guiding frame on the steel sheet pile.

[0009] Optionally, a rocker arm is arranged on the upper top frame. One end of the rocker arm is fixed on the upper top frame, and the other end is rotatably connected to the bottom frame.

[0010] By adopting the above technical solution, a rocker arm is arranged on the upper top frame, enabling the upper top frame to rotate relative to the bottom frame. When the rocker arm is inclined, the angle between the upper top frame and the bottom frame is set. The user can rotate the rocker arm to a position with the same inclination angle as the inner wall of the foundation pit, so that the steel sheet pile is inserted into the upper top frame and the bottom frame obliquely, and then the steel sheet pile can be arranged on the inclined inner wall of the foundation pit, improving the applicability of the guide frame.

[0011] Optionally, a guide frame is arranged on the upper top frame. The guide frame is located on one side of the upper top frame close to the bottom frame. The guide frame is a frame structure, and the length direction of the guide frame is parallel to the length direction of the rocker arm.

[0012] By adopting the above technical solution, by arranging a guide frame on the upper top frame, when the upper top frame rotates relative to the bottom frame, the guide frame can always face the bottom frame. When the steel sheet pile is inserted into the upper top frame, the steel sheet pile can slide along the length direction of the guide frame and be inserted into the bottom frame, achieving the effect of positioning the steel sheet pile, so that the steel sheet pile can enter the foundation pit in an inclined state.

[0013] Optionally, the fixing mechanism includes a mounting frame and a plurality of fixing bolts. The mounting frame is fixed on the bottom frame, and a plurality of mounting holes are provided on the mounting frame. The fixing bolts are inserted into the mounting holes and fixed on the ground.

[0014] By adopting the above technical solution, by arranging a mounting frame on the bottom frame, the user can install a plurality of fixing bolts on the mounting frame, so that the fixing bolts fix the mounting frame on the ground, and then keep the bottom frame stably connected to the ground.

[0015] Optionally, the support mechanism includes a hydraulic cylinder. One end of the hydraulic cylinder is connected to the upper top frame, and the other end is fixed on the ground. The hydraulic cylinder is used to be vertically arranged on the ground and support the upper top frame.

[0016] By adopting the above technical solution, by arranging a hydraulic cylinder on the upper top frame, the hydraulic cylinder can support the upper top frame, so that the upper top frame can maintain a stable position above the bottom frame. The user can adjust the distance between the upper top frame and the bottom frame by controlling the telescopic movement of the hydraulic cylinder, which is convenient for use.

[0017] Optionally, a shaft seat is fixed at the end of the piston rod of the hydraulic cylinder, and the shaft seat is rotatably connected to the upper top frame.

[0018] By adopting the above technical solution, by arranging a piston rod at the end of the hydraulic cylinder, when the bottom frame is inclined relative to the upper top frame, the user can adjust the length of the hydraulic cylinder, so that the hydraulic cylinder can be vertically fixed on the ground and provide support for the upper top frame.

[0019] Optionally, a bottom plate is fixed at the end of the cylinder body of the hydraulic cylinder, and the bottom plate is fixed on the ground by bolts.

[0020] By adopting the above technical solution, a bottom plate is arranged at the bottom of the hydraulic cylinder, and the user can fix the bottom plate on the ground through bolts, so that the hydraulic cylinder is detachably connected to the ground, improving the stability of the hydraulic cylinder on the ground.

[0021] Optionally, a plurality of support mechanisms are provided, and the plurality of support mechanisms are arranged along the edge of the upper top frame.

[0022] By adopting the above technical solution, by arranging a plurality of support mechanisms on the upper top frame, a plurality of hydraulic cylinders jointly support the upper top frame. When a steel sheet pile with a large weight is inserted into the upper top frame and abuts against the upper top frame, the upper top frame can maintain a stable position.

[0023] In summary, the beneficial technical effects of the present application are as follows:

[0024] 1. By arranging an upper top frame above the bottom frame, there is a gap between the upper top frame and the bottom frame. When the steel sheet pile is inserted into both the bottom frame and the upper top frame at the same time, the bottom frame and the upper top frame limit the steel sheet pile at the same time, thereby reducing the probability of the steel sheet pile shaking or deflecting during hoisting, and improving the positioning effect of the guiding frame on the steel sheet pile;

[0025] 2. By arranging a rocker arm on the upper top frame, the upper top frame can rotate relative to the bottom frame. When the rocker arm is inclined, the angle between the upper top frame and the bottom frame is set. The user can rotate the rocker arm to a position with the same inclination angle as the inner wall of the foundation pit, so that the steel sheet pile is inserted into the upper top frame and the bottom frame obliquely, and then the steel sheet pile can be arranged on the inclined inner wall of the foundation pit, improving the applicability of the guiding frame;

[0026] 3. By arranging a guiding frame on the upper top frame, when the upper top frame rotates relative to the bottom frame, the guiding frame can always face the bottom frame. When the steel sheet pile is inserted into the upper top frame, the steel sheet pile can slide along the length direction of the guiding frame and be inserted into the bottom frame, achieving the effect of positioning the steel sheet pile, so that the steel sheet pile can enter the foundation pit in an inclined state.

[0032] The following further describes the present application in detail with reference to the accompanying drawings.

[0033] An embodiment of the present application discloses a guiding frame for steel sheet pile construction. Referring to Figure 1 and Figure 2 , it includes a chassis 1, an upper top frame 2, a fixing mechanism 3 and a supporting mechanism 4. Both the chassis 1 and the upper top frame 2 are frame structures. The chassis 1 is arranged in contact with the plane of the foundation pit opening, and the upper top frame 2 is arranged above the chassis 1. The fixing mechanism 3 is connected to the chassis 1, and the fixing mechanism 3 is used to fix the chassis 1 to the ground. The supporting mechanism 4 is connected to the upper top frame 2, and the supporting mechanism 4 provides support for the upper top frame 2, so that the upper top frame 2 can be stably arranged above the chassis 1. The user hoists the steel sheet pile, and inserts the steel sheet pile vertically into the upper top frame 2 and the chassis 1, so that the upper top frame 2 and the chassis 1 can provide a limiting and guiding effect on the steel sheet pile. Then, the steel sheet pile can be vertically inserted into the foundation pit and arranged on the inner wall of the foundation pit. The user sets a plurality of steel sheet piles on the inner wall of the foundation pit, and the steel sheet piles provide support for the inner wall of the foundation pit, which can reduce the probability of the foundation pit collapse and improve the construction safety.

[0034] Referring to Figure 3 and Figure 4 , a rocker arm 22 is arranged on the upper top frame 2. One end of the rocker arm 22 is fixedly connected to the upper top frame 2, and the other end is rotatably connected to the chassis 1. The user rotates the upper top frame 2 to make the upper top frame 2 inclined relative to the chassis 1. When the steel sheet pile is inserted into the upper top frame 2, the steel sheet pile is inclined relative to the ground and slides in the upper top frame 2. When the steel sheet pile is inserted into both the chassis 1 and the upper top frame 2 at the same time, the steel sheet pile remains in an inclined state, and the user can insert the steel sheet pile into the foundation pit obliquely. When the inner wall of the foundation pit is inclined, the steel sheet pile can be installed on the inclined inner wall of the foundation pit.

[0035] Referring to Figure 3 and Figure 4 , a guiding frame 21 is arranged on the upper top frame 2. The guiding frame 21 is a frame structure, and the guiding frame 21 is installed on the upper top frame 2 on the side close to the chassis 1. The length direction of the guiding frame 21 is parallel to the length direction of the rocker arm 22. When the upper top frame 2 is inclined relative to the chassis 1, the length direction of the guiding frame 21 rotates with the rocker arm 22 and always faces the chassis 1. The guiding frame 21 plays a role in guiding the steel sheet pile. When the steel sheet pile is inserted into the upper top frame 2, the steel sheet pile can slide in the guiding frame 21 and be inserted into the chassis 1.

[0036] Referring to Figure 1 andFigure 2 , the fixing mechanism 3 includes a mounting frame 31 and a plurality of fixing bolts 32. The mounting frame 31 is of a long rod structure. One end of the mounting frame 31 is fixed on the chassis 1. A plurality of mounting holes 311 are formed in the mounting frame 31 along the length direction. Each fixing bolt 32 is inserted into one mounting hole 311. The fixing bolt 32 is used to penetrate the mounting frame 31 and be threadedly connected to the ground. The chassis 1 is fixed on the ground through the mounting frame 31.

[0037] Refer to Figure 1 and Figure 2 , the support mechanism 4 includes a hydraulic cylinder 41, a shaft seat 42 and a bottom plate 43. The bottom plate 43 is fixed on the cylinder block of the hydraulic cylinder 41. The shaft seat 42 is fixed on the piston rod of the hydraulic cylinder 41. The bottom plate 43 is fixed on the ground by bolts. The shaft seat 42 is rotatably connected to the upper top frame 2. The rotation axis formed by the shaft seat 42 and the upper top frame 2 is parallel to the rotation axis formed by the swing arm 22 and the chassis 1. A plurality of support mechanisms 4 can be provided. The plurality of support mechanisms 4 are arranged around the upper top frame 2, thereby improving the structural stability of the upper top frame 2. The user can rotate the upper top frame 2 and adjust the length of the hydraulic cylinder 41, so that the hydraulic cylinder 41 can be vertically fixed on the ground and support the upper top frame 2, thereby keeping the upper top frame 2 in better structural stability. When the steel sheet pile is inserted into the upper top frame 2, the upper top frame 2 can support the steel sheet pile and make the steel sheet pile slide obliquely into the chassis 1.

[0038] The implementation principle of the embodiment of the present application is as follows: By arranging the upper top frame 2 above the chassis 1, the steel sheet pile can be inserted into both the chassis 1 and the upper top frame 2 at the same time. Furthermore, the chassis 1 and the upper top frame 2 play a limiting role on the steel sheet pile, so that the steel sheet pile can accurately slide into the foundation pit from the chassis 1, improving the installation quality of the steel sheet pile. By rotatably connecting the chassis 1 and the upper top frame 2, the chassis 1 and the upper top frame 2 can be arranged at an angle. The user rotates the swing arm 22 to a position where the inclination angle is the same as the inclination angle of the inclined inner wall in the foundation pit, and inserts the steel sheet pile into the upper top frame 2, so that the steel sheet pile can slide obliquely into the chassis 1 and enter the foundation pit, thereby obliquely installing the steel sheet pile on the inner wall of the foundation pit.

[0039] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
