According to an aspect of the embodiment of the utility model, the utility model provides a steel bushing box obstacles removing device based on fig. 1 to fig. 3. The utility model discloses a steel bushing case device of removing obstacles mainly includes: a first set of panel structures comprising two opposing steel plates; a second set of panel structures comprising two opposing steel plates; the supporting pieces are welded and fixed with the first panel structure, the first panel structure and the second panel structure are welded into a ring, the supporting pieces comprise a plurality of groups of transverse supporting pieces arranged along the length direction at the same center distance and a plurality of groups of longitudinal supporting pieces arranged along the width direction at different center distances, a preformed groove is arranged at the bottom of the steel plate of the first panel structure, and a hoisting hole and a placing hole are arranged at the top of the steel plate of the first panel structure.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Fig. 1 is a plan view of a steel jacket box obstacle clearing device according to an embodiment of the present invention. Fig. 2 is a front view of a steel jacket box obstacle clearing device according to an embodiment of the present invention.

As shown in fig. 1 and 2, the steel box barrier clearing device may comprise two sets of panel structures welded to each other in a ring shape, one of the two sets of panel structures comprising two opposing steel plates, i.e. front plates 101, and the other of the two sets of panel structures comprising two opposing steel plates, i.e. side plates 102. For example, the front panel 101 and the side panel 102 are welded in a ring shape by 6mm fillet welding.

In a specific example of the embodiment of the present invention, the front panel 101 can adopt a Q235 steel plate with a planar size of 230 × 800cm and a thickness of 2cm, that is, the length of the front panel 101 is 800cm, the width is 230cm, and the thickness is 2 cm. In a specific example of the embodiment of the present invention, the side panel 102 may adopt a Q235 steel plate with a planar size of 76 × 740cm and a thickness of 2cm, that is, the length of the side panel 102 is 740cm, the width is 76cm, and the thickness is 2 cm.

It can be seen that the thickness of the front panel 101 and the side panel 102 may be the same, for example, both are 2cm, which can ensure convenient material drawing and convenient operation, and the steel hardness is the same, thereby enhancing the safety.

It can be seen that the length of the side panel 102, for example 740cm, may be smaller than the length of the front panel 101, for example 800cm, and accordingly a space for the pre-groove 203 is left at the bottom of the front panel 101. Discussion regarding the reserve tank 203 is discussed in detail later.

The width of the steel plates in the first group of panel structures is larger than the distance between the steel plates in the second group of panel structures. That is, as can be seen from fig. 2, the distance between the left and right side panels 102 is smaller than the width of the two front panels 101. Specifically, when the width of the front panel 101 is larger than the distance between the side panels 102, the front panel 101 on each side is respectively arranged at a certain distance more than the side panels 101 so as to facilitate welding, and the welding quality is ensured. For example, as shown in fig. 2, the width W of the front panel 101, for example 230cm, is greater than the distance d1 between the side panels 102, for example 220cm, so that a distance d2 of 5cm is added to the two sides, leaving a welding position.

The steel jacket box obstacle clearing device can also comprise a plurality of groups of supporting pieces, and the plurality of groups of supporting pieces can be divided into a plurality of groups of transverse road supporting pieces and a plurality of groups of longitudinal road supporting pieces in the width W direction and the length L direction shown in figure 2 in the steel jacket box obstacle clearing device. Specifically, in fig. 2, in the length L direction, the plural sets of supports include plural sets of lateral-lane supports disposed at the same center-to-center spacing. In fig. 2, the plurality of sets of supports include a plurality of sets of longitudinal-lane supports disposed at different center pitches in the width W direction. The details of the multiple sets of supports are discussed in detail below. As shown in fig. 2, the plurality of sets of supports includes a plurality of supports 103.

The support member 103 may be welded and fixed to the front panel 101. For example, the support member 103 and the front panel 101 may be welded together by 6mm fillet welding. For example, the support 103 may be a channel steel. More specifically, the support 103 may be a 14b channel steel.

As shown in fig. 2, a pre-groove 203 may be provided at the bottom of the steel plate of the front panel 101, and a lifting hole 201 and a resting hole 202 may be provided at the top of the steel plate of the front panel 101. In fig. 2, the lifting hole 201 may be above the resting hole 202.

Specifically, as shown in fig. 2, the pre-groove 203 may be at the bottom of the steel jacket box barrier clearing device. A reserved groove 203 with a certain size can be formed at the bottom of a steel plate of the steel jacket box obstacle clearing device according to the size and the actually measured position of the pipeline. As an example, the ratio of the length to the width of the pre-groove 203 may be 2:1, for example. Further, the dimensions of the reserve groove may be, for example, 60cm in length L1 and 30cm in width W1. The size of the reserve tank can be adjusted according to the size of the pipeline and the actually measured position, so that the reserve tank 203 is used for placing waste pipelines, and obstacle clearing operation of obstacles is facilitated. Particularly, because pipeline obstacles removing machinery can only excavate to the pipeline top, pipeline top to pipeline bottom need artifical excavation, if do not establish the artifical in-process that clears earth of reservation 203, the pipeline top to the earth of bottom probably collapse around the cell wall and influence the obstacles removing operation, set up behind the reservation and still can play the supporting role in the regional earthwork steel bushing box of pipeline.

As can be seen from the length L direction of the steel jacket box barrier clearing device of fig. 2, the lifting hole 201 can be above the resting hole 202. More specifically, the lifting hole 201 may be directly above the resting hole 202. The number of the lifting holes 201 and the resting holes 201 may be the same. For example, the number of the lifting holes 201 and the resting holes 201 may be 4 each.

The diameter of the resting hole 202 may be different from the diameter of the lifting hole 201. More specifically, the diameter of the resting hole 202 is larger than that of the hoist hole 201. More preferably, for example, the ratio of the diameter of the resting hole 202 to the diameter of the lifting hole 201 is 2: 1. By way of example, as shown in FIG. 2, the resting holes 202 have a diameter of 10cm and a radius of 5cm, while the lifting holes 201 have a diameter of 5cm and a radius of 2.5 cm. The hoisting hole 201 is mainly used for conveniently hoisting the steel jacket box obstacle clearing device, and the placing hole 202 is mainly used for fixing the steel jacket box obstacle clearing device by penetrating a placing carrying pole (not shown) on the ground.

As shown in fig. 2, the distance s1 from the center of the resting hole 202 to the top edge of the front panel and the distance s2 from the center of the lifting hole 201 to the top edge of the front panel may be different. Preferably, the ratio of the distance s2 from the center of the lifting hole 201 to the top edge of the front panel to the distance s1 from the center of the resting hole 202 to the top edge of the front panel may be 1: 2. For example, the center of the lifting hole 201 is 10cm from the top edge of the front panel by the distance s2, and the center of the resting hole 202 is 20cm from the top edge of the front panel by the distance s 1.

As shown in fig. 1 and 2, a plurality of groups of transverse road supporting pieces are arranged inside the steel jacket box obstacle clearing device in the length L direction of the steel jacket box obstacle clearing device. The plurality of sets of lateral lane supports includes a first number of sets of lateral lane supports. And in the width W direction of the steel sleeve box obstacle clearing device, a plurality of groups of longitudinal channel supporting pieces are arranged in the steel sleeve box obstacle clearing device. The plurality of sets of longitudinal lane supports includes a second number of sets of longitudinal lane supports. In particular, the first number may be different from the second number. Further, the first number may be larger than the second number. Still further, the ratio of the first number to the second number is 2: 1. For example, the plurality of sets of lateral track supports includes 8 sets of lateral track supports. The plurality of sets of longitudinal lane supports comprises 4 sets of longitudinal lane supports.

That is, in the length L direction of the steel jacket box obstacle clearing device, 4 sets of lateral track supporting members can be arranged inside the steel jacket box obstacle clearing device. In the width W direction of the steel jacket box obstacle clearing device, 8 groups of longitudinal channel supporting pieces can be arranged inside the steel jacket box obstacle clearing device. The ratio of the two numbers may be 1: 2.

Specifically, the center-to-center spacing between laterally disposed longitudinal track supports may be the same, defined as a first spacing d3, and the center-to-center spacing between centrally disposed longitudinal track supports is a second spacing d 4. Specifically, the size of the second distance d4 is different from the size of the first distance d 3. Further, the second spacing d4 is greater than the first spacing d 3. Specifically, the second spacing d4 is large to provide the necessary obstacle clearing operative surface, and the spacing is set to meet the calculation requirements. For example, the ratio of the first spacing d3 to the second spacing d4 may be 1: 3. More specifically, for example, the first distance d3 on both the left and right sides is 40cm, and the second distance is 120 cm.

Specifically, the center-to-center spacing between the lateral track supports is the same, defined as the third spacing d5, and the center of the steel pod barrier top and bottom edgemost lateral track supports are each the same spacing from the outer edge of the steel pod barrier, defined as the fourth spacing d 6. The third spacing d5 is different in size from the fourth spacing d 6. Further, the fourth spacing d6 is smaller than the third spacing d 5. The clearance design at this moment can make steel bushing box obstacles removing device accord with the minimum requirement of design calculation. For example, the ratio of the third spacing d5 to the fourth spacing d6 may be 2:1, for example. More specifically, for example, the third distances d5 are each 100cm, and the fourth distance d6 is 50 cm.

Specifically, the center-to-center spacing d5 (e.g., 100cm) between the lateral track supports is greater than the center-to-center spacing d3 (e.g., 40cm) between the laterally disposed longitudinal track supports, but less than the center-to-center spacing d4 (e.g., 120cm) between the centrally disposed longitudinal track supports.

In particular, the centre of the top and bottom most edge lateral track supports of the steel pod barrier unit are each spaced a distance d6 (e.g. 50cm) from the outer edge of the steel pod barrier unit less than the centre spacing d5 (e.g. 100cm) between the lateral track supports but greater than the centre spacing d3 (e.g. 40cm) between the laterally disposed longitudinal track supports.

Specifically, as shown in fig. 2, the left and right outermost longitudinal rail supports may be adjacent to the two side panels 102, respectively, but not in direct contact with the two side panels 102.

In the specific example, as shown in fig. 2, 4 sets of longitudinal track supports are provided in the length L direction of the steel jacket box barrier-clearing device. Wherein, in the width direction of fig. 2, from left to right, the first set of longitudinal rail supports is at a distance s3 from the left side edge of the front panel 101, the second set of longitudinal rail supports is at a distance s4 from the left side panel 102, and the third set of longitudinal rail supports is at a distance s5 from the right side edge of the front panel 101. Where the sum of s3 and d3 may be equal to s 5. For example, d3 is 40cm, s3 is 15cm, s4 is 50cm, s5 is 55cm, where the sum of s3 and d3 equals s5, which is 55 cm. That is, the distance s5 of the third set of longitudinal lane supports from the right side edge of the front panel 101 is the same as the distance (s3+ d3) of the second set of longitudinal lane supports from the left side edge of the front panel 101.

The length of each support member 103 in the multiple sets of support members can be the same as the width of the side panel 102, so that the support members 103 are ensured to be perpendicular to the front panel 101, correct stress is ensured, and obstacle removing safety is enhanced. For example, the length of the support member 103, for example 76cm, may be the same as the width of the side panel 102, for example 76cm, so as to ensure that the support member 103 is perpendicular to the front panel 101, ensure correct force and enhance the safety of obstacle clearing. The support member 103 may be welded and fixed to the front panel 101.

Furthermore, the embodiment of the utility model discloses a D300 gas steel pipe clearance can be used as the example.
