Description

Technical Field

[0001] This invention relates to the field of lifting platform cutting technology, and in particular to an adjustable lifting platform cutting device with internal concrete support in deep foundation pits. Background Technology

[0002] In the construction industry, it is often necessary to cut heavy objects such as concrete and granite, requiring the use of various cutting equipment. Electric wire saws are one such commonly used cutting equipment. Generally, heavy objects such as concrete and granite are supported and placed using a lifting platform, and then cut into different sizes by electric wire saws.

[0003] Existing methods for cutting concrete components, granite, and similar materials typically involve two parts: a temporary support frame and the cutting machine. The frame needs to be repeatedly erected during the cutting process. The cutting machine requires a lifting platform or other securing measures. When supporting heavy objects like concrete and granite, the machine's position is relatively fixed, making it difficult to horizontally adjust the platform and the weight on top. Furthermore, once the object is placed on the platform, the electric wire saw's installation position is also relatively fixed, hindering flexible horizontal adjustment and making it difficult to cut different areas of the concrete or granite surface. Additionally, a horizontal transport device is required after cutting.

[0004] Therefore, an adjustable lifting platform cutting device with internal concrete support for deep foundation pits is proposed, which serves as both a support frame and a cutting tool, while also taking into account the function of horizontal transportation. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of flexibly adjusting the horizontal position of electric wire saws, which makes it difficult to cut different positions on the surface of heavy objects such as concrete and granite. Therefore, this invention proposes an adjustable lifting platform cutting device with internal support for deep foundation pit concrete.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An adjustable lifting platform cutting device for deep foundation pit concrete internal support includes a base plate, a lifting frame installed at the top of the base plate, a support frame fixed at the top of the lifting frame, a first support plate slidably installed at the top of the support frame, a second support plate for bearing heavy objects installed at the top of the first support plate, a first driving mechanism between the bottom end of the first support plate and the support frame, a third support plate installed on one side of the first support plate, an electric wire saw installed at the top of the third support plate, and a second driving mechanism between the bottom end of the electric wire saw and the third support plate. The first driving moving mechanism includes guide rails fixed to both sides of the top of the support frame, first sliding grooves opened on both sides of the bottom of the first support plate for slidingly engaging and installing the guide rails, toothed plates fixed to both sides of the bottom of the first support plate, and gears rotatably installed on both sides inside the support frame and meshing with the bottom of the toothed plates.

[0007] As a further improvement of the present invention, rollers are rotatably installed at the four corners of the bottom end of the base plate, hydraulic telescopic rods are installed at an angle on the lifting frame, the support frame is a rectangular frame structure and is set horizontally, with first limiting grooves at both ends of its top end, and the toothed plate is set horizontally, with its bottom end sliding through the first limiting groove.

[0008] As a further improvement of the present invention, the cross-section of the guide rail and the first sliding groove are both T-shaped structures, and they are slidably snapped together and installed. The first support plate and the second support plate are both horizontally arranged, and support columns are fixed between the bottom ends of the second support plate and the top end of the first support plate.

[0009] As a further improvement of the present invention, a side plate is fixed in the middle of both sides of the bottom end of the support frame, and a rotating rod is rotatably installed between the two side plates. A motor is installed at one end of the rotating rod, and the gear is vertically fixed at both ends of the rotating rod.

[0010] As a further improvement of the present invention, fixing blocks are fixed at both ends of the side of the first support plate, a first connecting column is fixed on the outside of the fixing blocks, a second connecting column is fixed at one end of the outer side of the second support plate and at a position diagonally above the first connecting column, a third connecting column is fixed at one end of the outer side of the third support plate, and a fourth connecting column is fixed at the middle position of the outer side of the third support plate.

[0011] As a further improvement of the present invention, the third support plate is horizontally disposed below the outer side of the first support plate. A first pull plate is installed between one outer end of the third support plate and one outer end of the first support plate. Both ends of the first pull plate have first connecting holes. The third connecting post and the first connecting post slide through the first connecting holes. A second pull plate is installed between one outer end of the third support plate and one outer end of the second support plate. Both ends of the second pull plate have second connecting holes. The second connecting post and the fourth connecting post slide through the second connecting holes. Both ends of the first pull plate and the second pull plate are provided with first nuts with gaps. The first nuts are respectively connected to the surfaces of the first connecting post, the second connecting post, the third connecting post and the fourth connecting post. The second pull plate is inclinedly disposed above the first pull plate.

[0012] As a further improvement of the present invention, the second drive moving mechanism includes baffles fixed to both ends of the top of the third support plate, a second sliding groove formed inside the baffles, a second limiting groove formed at the top of the second sliding groove, a sliding block slidably installed inside the second sliding groove, a fastening bolt passing through the second limiting groove and connected to the top of the sliding block, a mounting rod fixed between the two sliding blocks, and a mounting plate for mounting the electric wire saw machine slidably installed on the surfaces of the two mounting rods.

[0013] As a further improvement of the present invention, the baffle is a rectangular plate structure and is horizontally arranged. The second sliding groove and the second limiting groove are both elongated structures and are horizontally arranged. The length of the second limiting groove is less than the length of the second sliding groove. The top two ends of the sliding block are provided with third connecting holes. The third connecting holes are threaded holes. The bottom thread of the fastening bolt is inserted into the third connecting hole.

[0014] As a further improvement of the present invention, the mounting plate is a rectangular plate structure and is slidably mounted on the top of the third support plate.

[0015] Beneficial effects: 1. This invention features a lifting frame, a hydraulic telescopic rod, and a support frame at the top of a base plate. A first support plate is slidably mounted on the top of the support frame via a first sliding groove and a guide rail. When heavy objects such as concrete or granite are placed on the top of the second support plate, an external controller operates a motor. The motor drives a rotating rod and gears to rotate, and the gears mesh to move a toothed plate. This allows the first support plate to move left and right along the first limiting groove and guide rail at the top of the support frame, thereby adjusting the horizontal position of the second support plate and the heavy object on its top. This facilitates horizontal adjustment of the concrete or granite, and the height can be adjusted via the lifting frame, hydraulic telescopic rod, and support frame, making it easier to cut and process heavy objects such as concrete and granite.

[0016] 2. In this invention, a third support plate is installed on one side of the first and second support plates via a first connecting column, a second connecting column, a third connecting column, a fourth connecting column, a first pull plate, and a second pull plate. Furthermore, the first and second pull plates are detachable, facilitating the installation and removal of the third support plate. Additionally, at the top of the third support plate, the position of a sliding block can be adjusted along a second sliding groove, and the sliding block is securely connected to the baffle via fastening bolts. Simultaneously, the position of the mounting plate is adjusted by sliding on the surface of the mounting rod and secured with a second nut. Thus, the electric wire saw is installed on the top of the mounting plate via connecting parts, facilitating the adjustment of the electric wire saw's horizontal position and enabling cutting and processing of different positions on the surface of heavy objects such as concrete and granite.
