Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment safety protection, and more specifically, to a method for preventing a high pressure spraying trolley from rolling over. Background Art

[0002] High-pressure jet grouting piles are used in many places during the construction of infrastructure projects. High-pressure jet grouting piles are constructed using a high-pressure jet trolley. The frame height of the high-pressure jet trolley is usually more than 20 meters, and the width of the chassis legs is only 3.7 meters after they are stretched out. The number of high-pressure jet grouting piles in engineering projects that usually use high-pressure jet grouting piles is relatively large. After the high-pressure jet trolley completes the construction of one pile, it jumps to the next pile position for construction. The high-pressure jet trolley moves frequently. The high-pressure jet trolley usually walks in a crawler-like manner. The trolley is high in height and has a small chassis. It sways left and right when walking, and has a high risk of overturning. It is easy to have a safety accident where the equipment overturns, causing damage to the surrounding personnel and property. If there are important structures near the construction area, the construction risk is increased.

[0003] At present, there is still no effective method to prevent the overturning of high-pressure spraying trolleys. Usually, management measures such as site leveling and compaction are taken at the construction site to prevent the high-pressure spraying trolleys from tipping over while moving. However, it still cannot effectively prevent the overturning of high-pressure spraying trolleys, and accidents of overturning of high-pressure spraying trolley equipment occur from time to time.

[0030] like Figures 1 to 3 As shown, the present invention provides a method for preventing a high-pressure spraying trolley from rolling over, which is achieved by a high-pressure spraying trolley anti-rollover device. The device includes a track 6 arranged outside the walking route of the high-pressure spraying trolley 1, a walking mechanism 5 walking along the track 6, and a horizontal beam 3 connecting the walking mechanism 5 to the legs of the high-pressure spraying trolley 1. The track 6 extends along the walking route of the high-pressure spraying trolley 1. The high-pressure spraying trolley 1 moves, and the walking mechanism 5 is driven by the beam 3 to move along the track 6, thereby preventing the high-pressure spraying trolley 1 from rolling over.

[0031] The track 6 includes a pair of track grooves 61 arranged at intervals relative to each other and a plurality of bottom plates 62 connecting the pair of track grooves 61 as a whole, and the plurality of bottom plates 62 are arranged at intervals along the extension direction of the track 6. The track 6 is arranged on the embedded block 4, and the embedded block 4 is embedded in the ground with the top surface protruding from the ground. A plurality of embedded blocks 4 are arranged, and the track 4 is detachably connected to the embedded block 4 through the bottom plate 62. A plurality of screws are embedded in the embedded block 4, and a plurality of reserved bolt holes 63 are arranged on the bottom plate 62. The embedded block 4 is bolted to the bottom plate 62. The track 6 is assembled from a plurality of units, and any two embedded blocks 4 form a unit. Figure 2 As shown, there are two units, each embedded block 4 corresponds to four embedded screws, and two embedded bolt holes are arranged on the bottom plate 62 arranged on both sides of each unit, which correspond to the two screws on the embedded block 4 to realize the assembly of the track 6, thereby realizing the turnover of materials. During the walking construction of the high-pressure spraying trolley, the embedded block 4 and the track 6 are installed with a set length, and then during the walking construction of the high-pressure spraying trolley 1, the track 6 unit at the rear of the walking mechanism is disconnected from the screw in real time, and the embedded block and track unit moved to the front of the walking mechanism are removed and installed, so as to realize the reuse of the track unit, so that there is basically no loss of components and materials, and the turnover utilization rate is high.

[0032] The walking mechanism 5 includes a vertical suspension rod 51 and a pair of bearings 52 arranged at the bottom of the suspension rod 51. The pair of bearings 52 are respectively slidably fitted in a pair of rail grooves 61. The suspension rod 51 is connected to the end of the cross beam 3. The end of the cross beam 3 is provided with a square-shaped space, in which the suspension rod 51 is inserted. The suspension rod 51 has a thread on the upper part of the cross beam 3. The steel pad 54 and the nut 53 are sequentially arranged from bottom to top. The steel pad 54 is limited to the top surface of the square-shaped space to achieve convenient and simple installation and removal of the suspension rod 51. A steel rod 55 is horizontally arranged at the bottom of the suspension rod 51, and a pair of bearings 52 are respectively arranged at both ends of the steel rod 55.

[0033] The end of the cross beam 3 on the track 6 side is connected to the upper part of the high pressure spraying trolley 1 through a steel cable 2.

[0034] The present invention pre-buries a plurality of embedded blocks 4 on both sides of the travel route of the high-pressure spraying trolley 1, and installs a track 6, then installs a crossbeam 3 on the support legs of the high-pressure spraying trolley 1, and installs a suspension rod 51 and a bearing 52 at the end of the crossbeam 3 to connect with the track 6. When the high-pressure spraying trolley 1 travels, the bearing 52 on the suspension rod 51 slides along the track groove 61 to prevent the high-pressure spraying trolley 1 from overturning.

[0035] Example

[0036] Take the construction of high-pressure jet grouting piles on the right bank of the Xiaoxiang Ship Lock Project as an example:

[0037] The right bank of the Xiaoxiang Ship Lock Project uses high-pressure jetting piles for anti-seepage. The left side of the anti-seepage line is a 110KV high-voltage line. The high-pressure jetting piles are constructed using a high-pressure jetting trolley 1. The high-pressure jetting trolley 1 itself is prone to equipment overturning accidents. In addition, there is a high-voltage line on the left side. If the high-pressure jetting trolley 1 overturns and presses the high-voltage line during construction, the consequences will be disastrous. In order to effectively prevent the overturning of the high-pressure jetting trolley 1 and prevent safety accidents, the high-pressure jetting trolley 1 anti-rollover device was used to achieve good results.

[0038] Embedded block 4 production:

[0039] The embedded block 4 is a concrete block with a side length of 100cm. During construction, a flat site is selected to draw the outline of the embedded block 4. The anti-cracking steel bars with a diameter of 8mm are tied at a vertical and horizontal spacing of 20cm. After the steel bar is tied, the template is installed. The template uses four bamboo plywood with a length and width of 1 meter. The back ribs are made of 5cm×10cm wooden squares. The template is reinforced with φ12 tension screws. After the template is installed, two φ20 lifting rings are embedded diagonally on the top surface for the transfer and lifting of the embedded block 4. Four φ22 screws are embedded in the middle for the subsequent fixing of the rail groove 61. After the embedded parts are installed and fixed, C25 concrete is poured and compacted with a vibrating rod. After the concrete is poured, it is wet-cured to the age.

[0040] like Figure 4 As shown, track 6 is processed and installed:

[0041] The length of a single rail groove 61 is 6 meters. The main beam of the rail groove 61 is made of two No. 12 channel steels. A bottom plate 62 is set at the end and the middle to fix the two channel steels. During processing, the notches of the two channel steels are opposite to each other, with a notch spacing of 5 cm, and welded to the bottom plate 62 steel plate. At the same time, a rib plate 64 is welded on the back of the channel steel at the position of the bottom plate 62. Two reserved bolt holes 63 are set on the bottom plate 62 steel plate outside the rail groove 61 to fix the rail groove 61 on the embedded block 4.

[0042] like Figure 5 As shown, beam 3 is processed and installed:

[0043] The crossbeam 3 is made of 200×200 H-shaped steel. A stiffening plate 31 is welded at an interval of 50 cm in the middle of the crossbeam 3 (H-shaped steel). The stiffening plate 31 is made of a 10 mm thick steel plate. A terminal steel plate 32 is first welded to the end of the crossbeam 3 on the side of the track 6, and then two longitudinal steel plates are welded on the terminal steel plate 32. The two longitudinal steel plates are 5 cm apart. Finally, a transverse steel plate is welded to the end of the longitudinal steel plate to form a slot-shaped steel box for installing the hanger 51. The longitudinal steel plate and the transverse steel plate together constitute the connecting steel plate 33. After the crossbeam 3 is processed, it is fixed to the leg crossbeam 3 of the high-pressure spraying trolley 1 with U-shaped bolts 7.

[0044] like Figure 6 As shown, the suspension rod 51 is processed and installed:

[0045] The suspension rod 51 is made of a φ25 round rod, the top is threaded, and a nut 53 and a steel pad 54 are installed. The bottom is welded into a circular ring. A φ40 steel rod 55 passes through the middle of the ring and is firmly welded to the suspension rod 51. The steel rod 55 is 11 cm long, and a bearing 52 with an outer diameter of 9 cm is installed at each end and firmly fixed.

[0046] Assembly and walking:

[0047] After all components are processed, first offset a certain distance (2.5m) according to the predetermined walking track of the high-pressure spraying trolley 1, lay out the lines and excavate the foundation trench for burying the embedded block 4. After the excavation of the foundation trench is completed, the embedded block 4 is hoisted into the foundation trench, and the plane position and elevation are adjusted (the embedded block 4 is appropriately higher than the ground to prevent soil from entering the track groove 61), and the foundation trench is backfilled to complete the embedding of the embedded block 4. After the embedded block 4 is buried, the processed track groove 61 is installed on the embedded block 4, and the bolts are tightened to fix the track groove 61. Install the high-pressure spraying trolley 1 to the starting position, and install and fix the beam 3 on the high-pressure spraying trolley 1, and then install the connecting wire cable 2 between the trolley frame and the beam 3. Pass the processed suspension rod 51 through the steel box at the end of the crossbeam 3 and hang it on the crossbeam 3. Move the trolley to insert the bearing 52 at the bottom end of the suspension rod 51 into the rail groove 61. Adjust the nut 53 at the top of the suspension rod 51 so that the bearing 52 of the bottom plate 62 of the suspension rod 51 can slide smoothly in the rail groove 61. After completing the installation of various components, the high-pressure spraying trolley 1 can move normally for construction. This embodiment is an implementation method of the anti-overturning device on one side of the high-pressure spraying trolley 1. If anti-overturning is required on both sides, anti-overturning devices can be installed on both sides.
