DETAILED DESCRIPTION

[0020] Embodiment 1:

[0021] See also Figure 1-4A lightweight, modular trench temporary protection equipment comprises two protective plates and a plurality of cross braces 40 arranged between the two protective plates. The protective plates comprise a cross beam 10, a column 20 and a baffle 30. The protective plates on each side comprise at least two cross beams 10, and the cross beams 10 on each side are arranged at intervals up and down. A plurality of connection seats 11 are fixedly arranged at intervals on the cross beams 10. The connection seats 11 are provided with transverse plug holes 12 on the outer side of the cross beams 10. A plurality of through holes 21 are axially provided on the columns 20. The columns 20 are connected to the connection seats 11 on the outer side of the cross beams 10. The pins 14 penetrate the plug holes 12 and the through holes 21, so as to connect and fix the columns 20 to the cross beams 10 on the protective plates. The baffle 30 is inserted between adjacent connection seats 11 and is located between the pins 14 and the first cross beam 2. The two ends of the cross brace 40 are respectively connected to the cross beams 10 on both sides, or are connected to the connection seats 11 on the cross beams 10 on both sides. Through the above structure, the protective equipment has a modular structure. In the present embodiment, each protective device includes 6 cross beams 10, 6 columns 20, 4 baffles 30, and at least 4 cross braces 40, wherein the protective plate on each side has 3 cross beams 10, 3 columns 20 and 2 baffles 30. When needed, the modules are assembled, and when needed for transportation and turnover, they are disassembled, thereby solving the problem of heavy weight and inconvenient transportation and turnover of the current support equipment.

[0022] For further information, see Figure 1 , 3 The connection seat 11 is located on the inner side of the cross beam 10 and is provided with a hinge hole 13. The two ends of the cross brace 40 are respectively provided with hinge sleeves 42. The hinge sleeves 42 are located in the connection seat 11. The pivot 43 penetrates the hinge hole 13 and the hinge sleeve 42 to hinge the cross brace 40 with the cross beam 10. Through the above structure, the connection support of the protective plates on both sides is realized.

[0023] During use, the hinge sleeves 42 at the two ends of the cross brace 40 are placed in the connecting seat 11, and the pivot 43 is inserted into the hinge hole 13 and the hinge sleeve 42. When dismantling, take out the pivot 43 and get final product, which is convenient for assembly and disassembly.

[0024] For further information, see Figure 1 The cross brace 40 is connected to the hinge sleeve 42 through a connecting rod 41. One end of the cross brace 40 is provided with a positive thread hole, and the other end is provided with a negative thread hole. The two connecting rods 41 are respectively threadedly connected with the positive thread holes and the negative thread holes at both ends of the cross brace 40. Through the above structure, the length adjustment of the cross brace 40 is realized.

[0025] When in use, the cross brace 40 is rotated. Since the two ends of the cross brace 40 are connected to the connecting rods 41 at both ends through positive and negative threads, the connecting rods 41 at both ends can be screwed outward or inward at the same time, thereby adjusting the length of the cross brace 40 to adapt to changes in the width of the groove.

[0026] See also Figure 1 , 3 In this embodiment, the connecting seat 11 includes two fixing plates, which are inserted and welded to the crossbeam 10, and a groove for clamping the column 20 is formed between the two fixing plates.

[0027] In another embodiment, the connection seat 11 is a U-shaped groove structure, and the connection seat 11 is welded and fixed to the outside of the cross beam 10, or the connection seat 11 is welded to the inside and outside of the cross beam 10. Through the above structure, the installation of the column 20 or the installation of the column 20 and the cross brace 40 can also be achieved.

[0028] It should be noted that, in addition to being connected to the connection seat 11 for support, the cross brace 4 can also directly lean against the inner side of the cross beam 10 .

[0029] In this embodiment, each side of the protective equipment is provided with three cross beams 10, and each cross beam 10 is provided with three connecting seats 11, which are composed of two fixing plates, which are fixed on the cross beam 10 by plug-in welding, and each side of the protective plate has three columns 20, and the three columns 20 on each side are respectively installed on the three connecting seats 11 on the three cross beams 10 through the pins 14, and the hinge sleeve 42 of the cross brace 40 is hinged to the connecting seat 11 through the pivot 43, and finally the baffle 30 is inserted between the adjacent connecting seats 11 and is located between the pins 14 and the first cross beam 2, so as to form an integral protective equipment unit. Figure 2 , 4 The connecting seats 11 on the two upper beams 10 are respectively provided with two plug holes 12, and the stability of the installation of the column 20 is improved by installing two pins 14.

[0030] Furthermore, one side of the latch 14 on the outer column 20 is bent, and a limiting hole 15 is provided at the other end near the column 20. The latch 14 on the middle column 20 is provided with limiting holes 15 on the outer side of the column 20. The limiting holes 15 are used to install a cotter pin to prevent the latch 14 from falling off.

[0031] In order to facilitate hoisting, a first hoisting hole 24 is provided at the upper end of the column 20 , and a second hoisting hole 31 is provided at the upper end of the baffle 30 .

[0032] Embodiment 2:

[0033] Based on Example 1, see Figure 2The column 20 is a tubular structure, and includes an upper column 22 and a lower column 23. A reinforcing column 50 is inserted inside the upper column 22 and the lower column 23, and a hole corresponding to the through hole 21 is provided on the reinforcing column 50. In this way, the height of the protective equipment can be adjusted according to different groove depths, thereby improving the adaptability to the site. When in use, the column 20 is respectively provided with a 1m and a 2m section. For grooves less than 2m deep, a 2m column is directly used; for grooves from 2m to 3m deep, a group of 2m and a group of 1m columns are used, and the baffle 30 is also a 2m piece and a 1m piece.

[0034] The working principle or action process of the utility model is as follows:

[0035] During installation, each modular component is transported to the work site and placed neatly in sequence on the ground outside the trench;

[0036] Lay the crossbeam 10 with the welded connection seat 11 flat on the ground, with the slot on the outside of the connection seat 11 facing upwards, insert the columns 20 into the slots on the outside of the connection seat 11 one by one, align the through hole 21 with the plug hole 12, pass the plug 14 through the plug hole 12 and the through hole 21, connect the column 20 with the crossbeam 10, insert the cotter pin into the limit hole 15, and the one-side frame is spliced. Each plug 14 forms a slot at the same time, and prepares for the later socket baffle 30. The other side of the frame is completed in the same way.

[0037] Use a small excavator to flip one side of the frame and lay it flat on the ground, align one end of the cross brace 40 with the connecting seat 11, and connect and fix it through the pivot 43. Similarly, fix the assembled frame on the other side and the other end of the cross brace to complete the splicing of the entire frame.

[0038] After the trench excavation is completed, the overall frame is hoisted to the trench through the first hoisting hole 24. The worker is located on the ground outside the trench and inserts the baffle 30 into the pin shaft slot reserved in the frame. The baffle 30 is made of bamboo plywood, and the overall support measures are installed.

[0039] When dismantling, the operation can be reversed.
