Description

Technical Field

[0001] This utility model belongs to the technical field of municipal engineering construction equipment, and in particular relates to an adjustable channel steel support quick pressing device. Background Technology

[0002] In the construction of urban drainage pipe networks for municipal stormwater and sewage separation renovation projects, trenches with an excavation depth of less than 3 meters are often supported by transverse plates or channel steel due to site limitations, ensuring sidewall safety. Currently, excavators are commonly used to directly press the channel steel into the soil to form a support structure. However, this method has significant drawbacks: in areas with hard soil, excavators lack sufficient power to press the channel steel into the predetermined depth. Furthermore, due to the lack of adjustable clamping structures for channel steel of different sizes, problems such as pressing angle deviation and lateral displacement easily occur when dealing with channel steel of different specifications or non-standard materials, resulting in the inability to guarantee support accuracy. If steel sheet pile driving machines are used instead, although the operation can be completed, their excitation force far exceeds the actual needs, equipment rental costs are high, and clamping modules are mostly of fixed specifications. For channel steel of different sizes, special clamps need to be customized or molds need to be frequently changed, making the operation cumbersome, time-consuming, labor-intensive, uneconomical, and a case of using excessive materials. Existing equipment is unable to accurately and quickly press in channel steel of different sizes. There is an urgent need for a special device with an adjustable structure to meet the needs of efficient construction of multi-specification channel steel in narrow spaces in municipal engineering projects.

[0031] See appendix Figures 1 to 4 This paper presents an illustrative embodiment of the adjustable channel steel support quick-pressing device proposed in this utility model. The adjustable channel steel support quick-pressing device includes a first plate 1, a second plate 2, a third plate 3, and an adjusting bolt 4.

[0032] See appendix Figure 1 The first plate 1 has a connecting hole 11 for connecting the hydraulic drill rod 61. Two second plates 2 are provided at both ends along the length of the first plate 1, and each second plate 2 has a groove 21 for fixing the channel steel 7 to be pressed in. Two third plates 3 are provided at both ends along the width of the first plate 1. See appendix. Figure 2 The first plate 1, the second plate 2, and the third plate 3 together constitute the main pressing structure of the device, which is a hollow cuboid structure with an open bottom and grooves on both sides. In this embodiment, two adjusting bolts 4 are provided, symmetrically arranged, and threadedly connected to the two third plates 3 respectively, to adjust and clamp the channel steel 7 to be pressed in. By tightening the adjusting bolts 4, fine adjustments can be made according to the actual size of the channel steel 7 to be pressed in, further enhancing the fixing effect of the channel steel 7 to be pressed in.

[0033] See appendix Figure 4 To facilitate adjustment, the adjustable channel steel support quick-pressing device of this embodiment also includes an adjustment knob 42. To facilitate clamping the channel steel 7 to be pressed in, the adjustable channel steel support quick-pressing device of this embodiment also includes a clamping plate 41. The adjustment knob 42 is fixedly installed on one end of the adjustment bolt 4, and the adjustment knob 42 is located outside the third plate 3. The clamping plate 41 is rotatably connected to the other end of the adjustment bolt 4, and the clamping plate 41 is located inside the third plate 3. The clamping plate 41 moves with the rotation of the adjustment bolt 4 to clamp the channel steel 7 to be pressed in.

[0034] The adjustable channel steel support quick-pressing device also includes an anti-slip pad 43, which is located on the side of the clamping plate 41 that contacts the channel steel 7 to be pressed in. The anti-slip pad 43 increases the friction with the surface of the channel steel 7 to be pressed in, preventing the surface of the channel steel 7 to be pressed in from being scratched during clamping.

[0035] See appendix Figure 3The structural perspective diagram of the device shows the connection relationship between the adjusting bolt 4, the clamping plate 41, the adjusting knob 42, and the anti-slip pad 43, as well as their connection relationship with the third plate 3. Another set of adjusting bolts 4, clamping plates 41, adjusting knobs 42, and anti-slip pads 43 (not shown in the attached diagram) are symmetrically arranged on the third plate 3 on the opposite side, which work together to clamp the channel steel 7 to be pressed in.

[0036] In some embodiments, the dimensions of the clamping plate 41 and the anti-slip pad 43 are designed to be slightly smaller than or equal to the third plate 3. See Appendix Figure 3 The dimensions of clamping plate 41 and anti-slip pad 43 are smaller than those of the third plate 3, see Appendix Figure 4 The dimensions of the clamping plate 41 and the anti-slip pad 43 are equal to those of the third plate 3. Specifically, the dimensions of the clamping plate 41 and the anti-slip pad 43 can be set according to actual construction needs to ensure that the contact area with the channel steel 7 is maximized (contact area ≥ 80%), while avoiding jamming of the channel steel insertion or the clamping plate 41 due to excessive size, thus forming a uniform clamping force distribution.

[0037] In this embodiment, the groove 21 of the second plate 2 is a trapezoidal groove 21, and the inclination angle of the trapezoidal groove 21 is 5°~15° (e.g., 10°). During the pressing process of the channel steel 7, the trapezoidal groove 21 can better guide the channel steel 7 into place, and when the channel steel 7 is under force, due to the inclination angle, it can convert some of the pressure into a squeezing force on the side of the channel steel 7, making the fit between the channel steel 7 and the groove 21 tighter and the fixing effect better. The inner wall roughness of the trapezoidal groove 21 is no greater than Ra3.2 to reduce the frictional resistance when the channel steel 7 is pressed in.

[0038] In some embodiments, the clamping plate 41 and the anti-slip pad 43 can form a set angle with the third plate 3. Specifically, the angle can be the same as the inclination angle of the trapezoidal groove 21, so that the channel steel 7 to be pressed in can enter the pressing device more smoothly. Specifically, the inclination angle can also be smaller than that of the trapezoidal groove 21, so as to ensure both smooth entry and clamping of the channel steel 7 to be pressed in. The clamping plate 41 and the adjusting bolt 4 can be fixedly connected or hingedly connected. When fixedly connected, the set angle between the clamping plate 41 and the anti-slip pad 43 and the third plate 3 is not adjustable. When hingedly connected, the set angle between the clamping plate 41 and the anti-slip pad 43 and the third plate 3 can be adjusted according to actual construction needs.

[0039] The first plate 1 is connected to the hydraulic gun's chisel 61 via a flange assembly, which includes two flanges 51 and connecting bolts 52. The flanges 51 are steel flanges, and the connecting bolts 52 are high-strength connecting bolts. A rubber gasket with a thickness of 5mm is provided between the two flanges 51. The rubber gasket prevents dust and dirt from entering the connection area during the pressing process and absorbs the lateral impact force generated by the gun's vibration.

[0040] The first plate 1, the second plate 2, and the third plate 3 are made of Q355B steel. The yield strength and tensile strength of Q355B steel can meet the requirements of use in complex environments such as humidity and acidity / alkali in municipal engineering.

[0041] The second plate 2 and the third plate 3 are both welded and fixed to the first plate 1. The surface of the second plate 2 is perpendicular to the surface of the first plate 1, and the surface of the third plate 3 is perpendicular to the surface of the first plate 1. Specifically, the second plate 2 and the third plate 3 are both welded and fixed to the first plate 1 using double-sided fillet welds, with a weld height of not less than 8mm. The first plate 1, the second plate 2, and the third plate 3 together form a bottom-opening [-shaped] frame structure. Preferably, the first plate 1, the second plate 2, and the third plate 3 can be made of integrally formed [-shaped] channel steel (such as 16# channel steel), which reduces welding steps while increasing structural strength by more than 25% and reducing weight by 15%.

[0042] In the above illustrative embodiments, the adjustable channel steel support rapid driving device has significant technical advantages and practical value: with the excitation force of the hydraulic jacking machine, the channel steel can be efficiently driven into various soil layers, and the device components can be flexibly replaced or the adjusting bolts can be finely adjusted according to different channel steel sizes, greatly improving applicability; it effectively overcomes the construction problem of channel steel being difficult to drive into hard soil layers, significantly speeding up construction and greatly improving construction efficiency; there is no need to rent large pile driving machinery, the device is easy to disassemble, and the jacking machine can be restored to normal use after disassembly, effectively reducing equipment rental costs and achieving outstanding economic benefits; the device has a scientific and reasonable structural design, is safe and reliable, has no safety risks during construction, and fully guarantees operational safety.

[0043] The following is in conjunction with the appendix Figures 1 to 4 The working process of one embodiment of the adjustable channel steel support rapid pressing device of this utility model will be described:

[0044] During installation, first, fix the pressing device to the hydraulic blasting machine's chisel 61 via the flange device 5 through the connecting hole 11 of the first plate 1. Tighten the connecting bolts 52 and ensure the rubber sealing gasket is sealed. Then, insert the channel steel 7 into the trapezoidal groove 21 of the second plate 2, using the inclined surface of the groove 21 for automatic guidance and positioning. During adjustment, rotate the adjusting knob 42 to move the adjusting bolt 4, so that the clamping plate 41 fits against the flange of the channel steel 7. Continue rotating to apply clamping force. If the channel steel has special specifications, the inclination angle of the clamping plate 41 can be adjusted and symmetrically clamped to ensure that the verticality deviation is ≤1°. During pressing, start the hydraulic blasting machine 6, using the excitation force of the chisel to drive the device to vibrate. The inner wall of the trapezoidal groove 21 reduces frictional resistance, allowing the channel steel 7 to be pressed into the soil layer. The inclined surface of the groove 21 converts part of the pressure into lateral extrusion force, which, together with the clamping force of the clamping plate 41, prevents displacement. During disassembly, loosen the adjusting knob 42, remove the connecting bolts 52 of the flange device 5, clean the device, and move to the next point. The blasting machine can then resume its crushing operation. The device uses a “positioning-clamping-pressing-disassembly” process, which significantly reduces the time required to press a single channel steel into place compared to traditional methods.

[0045] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0046] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
