Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a hose fixing device for a concrete pump truck. Background Art

[0002] During the concrete pouring construction in higher and narrower locations (such as subway foundation pit retaining walls, ground, power transmission and transformation project foundations, etc.), since the pouring locations are often difficult to stand at or the height is high, there is a safety risk of abrasions and falls for workers. Therefore, a sleeve device suitable for pump pipes is required to ensure personnel safety. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a hose fixing device for a concrete pump truck.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a hose fixing device for a concrete pump truck, comprising a fixing chain, a clamping piece, a screw rod and a fixing rod, wherein the clamping piece is rotatably mounted on one end of the fixing chain, the clamping piece is provided with a clamping ring, and a connecting frame is rotatably provided on the other end of the fixing chain, the screw rod is mounted on the connecting frame, and the fixing rod is mounted on the screw rod through a threaded connection.

[0005] As a further description of the above technical solution:

[0006] The engaging piece has a certain curvature, and the curvature is adapted to the hose.

[0007] As a further description of the above technical solution:

[0008] A notch is provided on the snap ring.

[0009] The utility model has the following beneficial effects:

[0010] The fixing chain is wrapped around the hose so that the clamping piece is clamped on the hose, and then the clamping ring is matched with the notched screw rod, so that during the concrete pouring construction operation, the operator stands in a safe position. By using this fixing device to guide the end hose, the operator does not need to stand at the edge of the building and hold the end hose to perform the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 The figure is a structural schematic diagram of a hose fixing device for a concrete pump truck according to the present invention.

[0012] Legend:

[0013] 1. Fixed chain; 2. Clamping piece; 3. Screw rod; 4. Fixed rod; 5. Clamping ring; 6. Connecting frame. DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] Reference Figure 1 As shown, a hose fixing device for a concrete pump truck consists of a fixing chain 1, a clamping member 2, a screw rod 3 and a fixing rod 4. The clamping member 2 is rotatably mounted on one end of the fixing chain 1, and a clamping ring 5 is provided on the clamping member 2. A connecting frame 6 is rotatably provided on the other end of the fixing chain 1. The screw rod 3 is mounted on the connecting frame 6, and the fixing rod 4 is mounted on the screw rod 3 through a threaded connection.

[0016] The engaging member 2 has a certain curvature, which is adapted to the hose.

[0017] The snap ring 5 is provided with a notch.

[0018] Instructions:

[0019] Wrap the fixing chain 1 around the hose to lock the clamping member 2 on the hose, then fit the clamping ring 5 through the notched screw rod 3, and then rotate the fixing rod 4 to squeeze the clamping ring 5, thereby fixing the hose.

[0020] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
