Detailed Description
The following detailed description of the preferred embodiments of the utility model refers to the accompanying drawings.
As shown in fig. 1-4: the utility model provides a welded fastening device is exempted from in steel pipe tie under water, establishes sleeve 5 and the adjacent sleeve 5's of fixed connection connecting rod 6 on steel pipe 1 including the cover, and adjacent sleeve 5 sets up relatively, and the both ends of connecting rod 6 weld with the section of thick bamboo wall of two adjacent sleeves 5 respectively to realize the tie between steel pipe 1, also can two connecting rods 6 cross-fixation can be more firm.
Consequently, the internal diameter of collet 2 is slightly bigger than the external diameter of steel pipe 1 and some, can 1cm big, and collet 2's external diameter is compared not too big than the internal diameter, and too big 4 can be installed apart from steel pipe 1 far away, when sleeve 5 and 4 locks of wedge, push away from steel pipe 1 with wedge 4 on the contrary, can't play fixed effect, and consequently collet 2's inside and outside diameter difference can not be too big, can about 15cm big.
The upper end face of the bottom support 2 is provided with a plurality of track grooves 3 extending along the radial direction of the steel pipe 1, and the plurality of track grooves 3 are distributed around the circumferential direction of the steel pipe 1. The track groove 3 can be a groove formed between two limiting plates, the groove is uniformly distributed around the circumference of the steel pipe 1, and the bottom end of the wedge-shaped block 4 is positioned in the groove and slides inwards along the groove when the sleeve 5 descends. The track groove 3 can also be a groove formed in the upper end surface of the bottom support 2, the groove is distributed around the circumference of the steel pipe 1, and the bottom end of the wedge-shaped block 4 is positioned in the groove and slides inwards along the groove when the sleeve 5 descends.
The track groove 3 is internally provided with a wedge block 4 in a sliding way, the wedge block 4 is perpendicular to the track groove 3 and is parallel to the steel pipe 1, and the wedge block 4 becomes thicker from high to low along the height direction. Wherein, single wedge 4 can be the iron plate, and the section of wedge 4 is right triangle, and short right-angle side is located track groove 3, and long right-angle side is parallel with steel pipe 1, and the specific size changes according to the quantity change of track groove 3's setting. For example, 12 track grooves 3 are arranged on the base plate 2, and the height of the track groove 3 is 2cm, so that the long side of the wedge block 3 is 20cm, the short side of the wedge block 3 is 1cm, and the thickness of the wedge block is 1/12 of the diameter of the steel pipe 1. According to the actual demand, the number of the track grooves 3 is at least 3, the more the track grooves 3 are, the more the wedge blocks 4 are, which means that the sleeve 5 is locked with the wedge blocks 4, so that the sleeve 5 is more firmly fixed on the steel pipe 1. When the wedge blocks 4 are too few, the sleeves 5 may be deviated or inclined, so that the sleeves 5 are not firmly fixed, and the steel pipes 1 are not firmly connected in a parallel manner, thereby deteriorating the bearing capacity and stability of the bridge construction work platform.
In addition, the outer end face of the bottom support 2 is provided with a baffle along the circumferential direction, the baffle seals the outer end of the track groove 3, and the wedge-shaped block 4 is prevented from falling off. In addition, can take interference fit between track groove 3 and the wedge 4, wedge 4 can not drop from track groove 3 outer end, when sleeve 5 transfers in addition, receives the effort wedge 4 of 5 section of thick bamboo walls of sleeve and inwards slides. The wedge-shaped block 4 can be restrained by the height change of the bottom of the track groove 3, and the bottom of the track groove 3 is gradually reduced from the outer end to the inner end, so that the wedge-shaped block 4 can only move in a single direction.
According to the bridge work progress, at first with 1 back of piling of steel pipe, carry out the tie between the steel pipe 1 and ally oneself with, concrete tie position needs the location, and collet 2 establishes the preset position of 1 tie of steel pipe through 7 covers of positioning mechanism, and a plurality of positioning mechanism 7 around collet 2's circumference evenly distributed, and collet 2 can be located the position of tie between the steel pipe 1 steadily unchangeably under the cooperation of positioning mechanism 7. After the sleeve 5 and the wedge block 4 are locked and fixed, the positioning mechanism 7 can be removed. The positioning mechanism 7 comprises a limiting rope, hooks are arranged at two ends of the limiting rope, one end of the limiting rope is hooked on the bottom support 2, and the other end of the limiting rope is hooked at the top of the steel pipe 1. Before construction, the steel pipe subjected to parallel connection is subjected to water depth measurement, the mounting height of the underwater steel pipe parallel connection welding-free fixing device is determined according to measurement data, the length of a limiting rope in a positioning mechanism 7 is determined, the position of a bottom support 2 is limited according to the length of the limiting rope, and therefore the final mounting position is determined.
For hanging on collet 2 in order to make things convenient for the couple in the positioning mechanism 7, evenly seted up a plurality of on collet 2 and get in touch complex hanging hole, a plurality of hanging holes distribute along collet 2's circumference, for the collet 2 of holding up firmly, the hanging hole sets up three at least.
The use method of the underwater steel pipe parallel connection welding-free fixing device comprises the following steps: firstly, measuring the water depth, and determining the installation position of the underwater steel pipe parallel connection welding-free fixing device. Secondly, under the cooperation of positioning mechanism 7, transfer collet 2 to the preset position of 1 parallel connection of steel pipe along 1 concentric axis of steel pipe. And finally, placing the sleeve 5, gradually enabling the bottom end of the wedge block 4 to approach the steel pipe 1 from the outer side along the track groove 3 along with the descending of the sleeve 5, and finally fixing the sleeve 5 on the steel pipe 1 to finish the parallel connection and fixation of the underwater steel pipe 1.
