Description

Technical Field

[0001] The utility model relates to a concrete conveying pipe positioning device, in particular to a foundation construction protection device for a coal hopper in a dumper room of a coal conveying system, belonging to the technical field of coal hopper casting. Background Art

[0002] The tipper room is an important part of the coal transportation system of the thermal power project. After the coal hopper of the tipper room is supported, concrete pouring construction is required. During this period, the staff will reserve a feed port on the top of the template in advance to facilitate the later grouting construction; because the feed port is distributed in a sloped shape, the overhead crane feed pump is prone to shaking during grouting, causing concrete to fall outside the template, and the coal hopper is deep, without any protective measures in the middle. The large shaking of the overhead crane feed pump poses certain safety hazards. Utility Model Content

[0003] The technical problem to be solved by the utility model is: to overcome the shortcomings of the existing technology and provide a foundation construction protection device for the coal hopper of the coal conveying system dumper room to avoid the situation where the overhead crane feeding pump shakes significantly and causes material overflow, thereby ensuring the safety and stability of construction.

[0004] The technical solution adopted by the utility model to solve the technical problem is:

[0005] A protective device for the foundation construction of a coal hopper in a dumper room of a coal conveying system comprises a material guide cylinder and a positioning ring. A positioning ring is provided above the material guide cylinder, and a connecting column is provided between the material guide cylinder and the positioning ring. A positioning plate is provided on one side of the outer wall of the positioning ring, and a support column is provided on the other side of the outer wall of the positioning ring. The positioning plate is fixedly connected to the ground by anchor bolts.

[0006] The end of the support column spans the beam above the coal hopper, the outer wall of the beam is sleeved with a U-shaped frame, the end of the support column passes through the upper part of the U-shaped frame and is fixed together by bolts.

[0007] A through hole is dug on the top of the U-shaped frame, and a guide sleeve is arranged outside the through hole, and a bolt is arranged outside the guide sleeve.

[0008] The inner diameter of the material guiding cylinder matches the inner diameter of the positioning ring, and the inner diameter of the material guiding cylinder is larger than the outer diameter of the material conveying pipe.

[0009] The positive beneficial effects of the utility model are:

[0010] 1. The utility model provides a positioning plate and a support column on the outer wall of the positioning ring, so that the positioning ring can be stuck between the ground and the crossbeam of the coal hopper to play a limiting role. By providing a material guide barrel below the positioning ring, the lower end of the overhead crane feed pump is extended into the material guide barrel, thereby avoiding the feed pump from shaking significantly during the grouting process and achieving accurate feeding.

[0011] 2. The utility model provides a U-shaped frame on the outer wall of the beam, and the top of the support column passes through the U-shaped frame, so that the positioning ring can be fixed, ensuring the stability and safety of the construction. It is easy to use, simple to operate, and easy to promote. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a diagram of the use state of the utility model;

[0013] Figure 2 It is a structural diagram of the utility model;

[0014] Among them: 1- material guide cylinder, 2- connecting column, 3- positioning ring, 4- positioning plate, 5- support column, 6- U-shaped frame, 7- guide sleeve, 8- bolt, A- material delivery pipe, B- crossbeam. DETAILED DESCRIPTION

[0015] The present invention will be further explained and illustrated below with reference to the accompanying drawings:

[0016] For example, see Figure 1-Figure 2 A protective device for the foundation construction of the coal hopper in the dumper room of a coal conveying system includes a guide barrel 1 and a positioning ring 3. A positioning ring 3 is arranged above the guide barrel 1, and a connecting column 2 is arranged between the guide barrel 1 and the positioning ring 3. A positioning plate 4 is arranged on one side of the outer wall of the positioning ring 3, and a support column 5 is arranged on the other side of the outer wall of the positioning ring 3. The positioning plate 4 is fixedly connected to the ground by anchor bolts.

[0017] The end of the support column 5 spans the beam B above the coal hopper, and a U-shaped frame 6 is sleeved on the outer wall of the beam B. The end of the support column 5 passes through the upper part of the U-shaped frame 6 and is fixed together by bolts 8.

[0018] A through hole is dug at the top of the U-shaped frame 6 , a guide sleeve 7 is provided outside the through hole, and a bolt 8 is provided outside the guide sleeve 7 .

[0019] The inner diameter of the material guide cylinder 1 matches the inner diameter of the positioning ring 3 , and the inner diameter of the material guide cylinder 1 is larger than the outer diameter of the material delivery pipe A.

[0020] In the above description, when the positioning plate is fixed to the ground by anchor bolts, the support column is also fixedly connected to the U-shaped frame by bolts. At this time, the lower end of the material guide barrel is located at the internal position of the feed port.

[0021] When in use, after fixing the positioning plate and support column outside the positioning ring, extend the lower end of the overhead crane feed pump into the guide barrel until the bottom of the feed pump is exposed to the bottom of the guide barrel, and then grouting construction can be carried out.

[0022] The utility model provides a positioning plate and a support column on the outer wall of the positioning ring, which can make the positioning ring be stuck between the ground and the cross beam of the coal drop hopper to play a limiting role. By arranging a material guide cylinder below the positioning ring, the lower end of the overhead crane feed pump is extended into the material guide cylinder, which avoids the feed pump from shaking significantly during the grouting process. At the same time, it also realizes accurate feeding, ensures the stability and safety of construction, is easy to use, simple to operate, and easy to promote.
