Description

Technical Field

[0001] The utility model relates to a spring pipe clamp for a heat tracing pipe of a rigid trolley wire, which can quickly install a heat tracing pipe (also called a heating pipe) on the rigid trolley wire and belongs to the technical field of conductive connection. Background Art

[0002] In winter in northern China, the low-temperature period is relatively long. Affected by weather such as freezing rain, snowfall, and frost, outdoor open-air running equipment with rigid trolley wires as conductive carriers in most iron and steel enterprises frequently experiences power-off failures and is difficult to operate stably. To solve such problems, it is necessary to install a heat tracing pipe on the rigid trolley wire. The shape of the rigid trolley wire is the same as that of a steel rail (please refer to Figure 1 ), which includes a rail head 1-1, a rail web 1-2, and a rail base 1-3. The rail web 1-2 is a plate-like structure perpendicular to the horizontal plane, and its length direction is the running direction of the equipment. The rail head 1-1 and the rail base 1-3 are respectively located at the top and bottom of the rail web 1-2. The width of the rail head 1-1 is greater than the thickness of the rail web 1-2, and the width of the rail base 1-3 is greater than the width of the rail head 1-1. The entire rigid trolley wire is symmetric left and right. Generally, the heat tracing pipe is connected to the rigid trolley wire through a plurality of pipe clamps arranged densely along the rigid trolley wire. The existing pipe clamps are connected to the rigid trolley wire through bolts. Due to the large number of pipe clamps, the bolt connection method takes a long construction time, and the rigid trolley wire needs to be powered off during the installation process, which seriously affects the normal progress of industrial production. Therefore, it is very necessary to design a pipe clamp that is convenient and fast to install. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a spring pipe clamp for a heat tracing pipe of a rigid trolley wire aiming at the disadvantages of the prior art, so as to improve the installation efficiency of the heat tracing pipe, reduce the power-off construction time, and ensure the normal progress of industrial production.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A spring pipe clamp for a heat tracing pipe of a rigid trolley wire includes a C-shaped spring and two C-shaped clamping plates. The two C-shaped clamping plates are symmetrically arranged on both sides of the rail web of the rigid trolley wire, and their openings face the rail web. Each C-shaped clamping plate internally clamps a heat tracing pipe. The C-shaped spring is sleeved outside the rail base of the rigid trolley wire, and both ends of the C-shaped spring are respectively connected to the lower ends of the two C-shaped clamping plates. The elastic force of the C-shaped spring makes the heat tracing pipe clamped inside the C-shaped clamping plate in close contact with the side wall of the rail web.

[0006] For the above spring pipe clamp for a heat tracing pipe of a rigid trolley wire, the upper end of the C-shaped clamping plate is provided with a curled edge that turns outward.

[0007] The above-mentioned heat tracing pipe spring clip for rigid trolley wire, the C-shaped spring includes a bottom arc plate and two rail clamping plates. The bottom arc plate is located below the rail bottom of the rigid trolley wire with its concave surface facing upward. The two rail clamping plates are symmetrically arranged on both sides of the rail waist and are in contact with the upper surface of the rail bottom. One end of each of them is connected to both ends of the bottom arc plate respectively, and the other end extends to the side of the rail waist and is connected to the lower end of each of the two C-shaped clamping plates respectively.

[0008] The above-mentioned heat tracing pipe spring clip for rigid trolley wire, each rail clamping plate is connected to the corresponding C-shaped clamping plate through a transition arc plate, and the convex surface of the transition arc plate faces the rail waist.

[0009] The above-mentioned heat tracing pipe spring clip for rigid trolley wire, the C-shaped spring and the C-shaped clamping plate are of an integral structure.

[0010] The above-mentioned heat tracing pipe spring clip for rigid trolley wire, the C-shaped spring and the C-shaped clamping plate are made of an elastic stainless steel strip.

[0011] The above-mentioned heat tracing pipe spring clip for rigid trolley wire, the central angle of the C-shaped clamping plate is greater than 180 degrees.

[0012] The above-mentioned heat tracing pipe spring clip for rigid trolley wire, the cross-section of the bottom arc plate is in the shape of a circular arc, and the center of the circular arc is on the median line of the rail waist.

[0013] The utility model uses two C-shaped clamping plates to clamp two heat tracing pipes, and relies on the elastic force of the C-shaped spring to make the two heat tracing pipes closely adhere to the rail waist of the rigid trolley wire. It can not only ensure the heating effect, prevent power failure caused by the rigid trolley wire icing, but also be convenient and fast to install, greatly improve the installation efficiency of the heat tracing pipe, reduce the power outage construction time, and ensure the normal progress of industrial production.

[0022] The utility model provides a heat tracing pipe spring clip for a rigid trolley wire aiming at the problems existing in the prior art. The pipe clip is simple to manufacture, has a stable structure and is convenient to install. Compared with the bolt fixing method, it can save a large amount of power outage installation time and ensure the stable operation of production.

[0023] See Figures 1 - 4 , the utility model is made of a section of elastic stainless steel strip. The stainless steel strip is made into an approximately U-shaped shape through stamping and bending. The processed stainless steel strip can be divided into nine sections according to the shape, namely the bottom arc plate 3-1, two rail clamping plates 3-2, two transition arc plates 3-3, two C-shaped clamping plates 3-4 and two curled edges 3-5. Among them, the bottom arc plate 3-1, two rail clamping plates 3-2 and two transition arc plates 3-3 form a C-shaped spring with an upward opening.

[0024] Figure 3 , Figure 4 shows that the bottom arc plate 3-1 is located below the rail base 1-3 of the rigid trolley wire. Its upper surface is concave and does not contact the bottom surface of the rail base 1-3. The cross-section of the bottom arc plate 3-1 is in an arc shape, and the center of the arc is on the center line of the rail web 1-2. When the spring pipe clip 3 is not installed, the distance (chord length) between the two ends of the bottom arc plate 3-1 is less than the width of the rail base 1-3; after the spring pipe clip 3 is installed, the distance between the two ends of the bottom arc plate 3-1 is greater than or equal to the width of the rail base 1-3, and the bottom arc plate 3-1 is in a stretched state, and its two ends can provide an elastic force to tighten towards the rail web 1-2.

[0025] The two rail clamping plates 3-2 are symmetrically arranged on both sides of the rail web 1-2 and are respectively connected to the two ends of the bottom arc plate 3-1. The shape of the rail clamping plate 3-2 matches the shape of the upper surface of the rail base 1-3. In the stretched state of the spring pipe clip 3, the elastic force of the bottom arc plate 3-1 makes the rail clamping plate 3-2 abut against the upper surface of the rail base 1-3, and the end of the rail clamping plate 3-2 not connected to the bottom arc plate 3-1 extends to the side of the rail web 1-2.

[0026] The lower ends of the two transition arc plates 3-3 are respectively connected to the two rail-holding plates 3-2, and the upper ends are respectively connected to the lower ends of the two C-shaped clamping plates 3-4. The convex surfaces of the transition arc plates 3-3 face the rail web 1-2, that is, they bend outward at the rail web 1-2. Its function is to connect the C-shaped clamping plate 3-4 and the rail-holding plate 3-2 together. When the spring pipe clamp 3 is not installed, the radius of curvature of the transition arc plate 3-3 is greater than that of the transition arc plate 3-3 after the spring pipe clamp 3 is installed, so as to provide an upward elastic force.

[0027] The lower end of the C-shaped clamping plate 3-4 is connected to the upper part of the transition arc plate 3-3, and the upper end is provided with a curled edge 3-5. The C-shaped clamping plate 3-4 can be regarded as an upward extension of the transition arc plate 3-3. The inner wall of the C-shaped clamping plate 3-4 fits the surface of the tracing heat pipe 2. When the spring pipe clamp 3 is not installed, the radius of curvature of the C-shaped clamping plate 3-4 is smaller than the outer diameter of the tracing heat pipe 2, and the central angle of the C-shaped clamping plate 3-4 is greater than 180 degrees, which can firmly bind the tracing heat pipe 2 and make the tracing heat pipe 2 closely abut against the side wall of the rail web 1-2.

[0028] The curled edge 3-5 is at the edge part of the entire spring pipe clamp 3. This is the force application part when installing the spring pipe clamp 3. The safety of the edge of the metal plate after curling treatment is improved, and it is not easy to cut the operator.

[0029] An embodiment of the present utility model is as follows:

[0030] The model of the rigid trolley wire 1 is JGH-I. The width of the rail head 1-1 is 22 mm, and the height is 16 mm; the height of the rail web 1-2 is 25.5 mm, and the width is 6 mm; the width of the rail bottom 1-3 is 52 mm, and the height is 11 mm;

[0031] The pipe diameter of the tracing heat pipe 2 is φ16 mm;

[0032] The spring pipe clamp 3 is made of a 200 mm × 50 mm × 0.8 stainless steel strip;

[0033] The arc length of the bottom arc plate 3-1 is 60 mm, and the central angle is 100°;

[0034] The length of the rail-holding plate 3-2 is 23.5 mm;

[0035] The arc length of the transition arc plate 3-3 is 9.5 mm, and the central angle is 180°;

[0036] The arc length of the C-shaped clamping plate 3-4 is 29 mm, and the central angle is 225°;

[0037] The arc length of the curled edge 3-5 is 7.5 mm, and the central angle is 300°.
