Description

Technical Field

[0001] This utility model relates to the technical field of tamping picks for tamping machines, and in particular to a tamping pick for a small railway tamping machine. Background Technology

[0002] Tamping machines are mainly used in railway or building construction to compact the ballast or concrete under the sleepers to enhance the stability and density of the track or building foundation. However, the tamping pick of modern tamping machines consists of an outer shell and an inner core. Because the tamping pick is under constant vibration, when replacing it, not only the outer shell but also the inner core needs to be replaced, which greatly increases the cost. Moreover, small tamping machines mostly use tamping picks individually and cannot be used in combination, which is inefficient in some practical situations.

[0003] Therefore, there is a need to invent a tamping pick for a small railway tamping machine. This equipment can use the first tamping pick part or the second tamping pick part independently, or it can combine the first tamping pick part and the second tamping pick part together through an external connection, so that the first tamping pick part and the second tamping pick part can work simultaneously, improving work efficiency. The tamping pick rod of this equipment is machined and brazed with hard alloy to improve the service life of the product and reduce the replacement frequency, thereby reducing costs. The first tamping pick part and the second tamping pick part of this equipment have simple structures, are easy to use, and have low manufacturing costs. Furthermore, the tamping pick of this equipment is machined and brazed with hard alloy to improve the service life of the product and reduce the replacement frequency, thereby reducing costs. Summary of the Invention

[0005] The technical solution used in this utility model is: a tamping pick for a small railway tamping machine, comprising: a first tamping pick part, an external connection part, and a second tamping pick part;

[0012] Preferably, the first tamping pick further includes: a tamping pick rod;

[0013] The tamping rod is inserted into the cylindrical sleeve.

[0014] Preferably, the first tamping pick further includes: a lead screw moving mechanism, a slider, a rectangular block, and a handwheel;

[0015] The frame of the lead screw moving mechanism is fixedly connected to one of the square blocks. The shaft of the lead screw of the lead screw moving mechanism is fixedly connected to the handwheel. The screw threads of the lead screw moving mechanism rotate in opposite directions. The threads at both ends of the lead screw moving mechanism are respectively threaded with a slider. Each slider is slidably mounted on the bracket of the lead screw moving mechanism. A rectangular block is fixedly installed on the inner side of each slider. A protrusion is provided on the inner side of each slider.

[0016] Preferably, the external part includes: a connecting frame, a handle, an electric cylinder, a limiting groove, and a side connecting mechanism;

[0017] The connecting frame is fixedly equipped with a handle; there are two electric cylinders, and the cylinder bodies of the two electric cylinders are respectively connected to the connecting frame through movable connecting parts.

There are two limiting frames, each of which is attached to the predetermined installation area of ​​the connecting frame by a fastening mechanism. A cylindrical shaft is slidably installed in the sliding groove of each limiting frame. There are two cylindrical shafts, and the two cylindrical shafts are fixedly installed on both sides of the insert block.

[0020] The advantages of this utility model compared with the prior art are:

[0021] 1. This equipment can be used independently of the first or second tamping pick section, or it can be combined with the first and second tamping pick sections through an external connection, allowing them to work simultaneously and improving work efficiency. The tamping pick rod of this equipment is machined and brazed with hard alloy to extend the product's service life and reduce the frequency of replacement, thereby reducing costs. The first and second tamping pick sections of this equipment have simple structures, are easy to use, and have low manufacturing costs.

[0022] When using either the first or second tamping tool separately, the tamping tool rod is first manually inserted into the cylindrical sleeve. Since the inner diameter of the cylindrical sleeve is the same as the size of the upper cylinder of the tamping tool rod, and the inner side of the cylindrical sleeve is equipped with anti-slip strips, the tamping tool rod will not easily fall off after being inserted into the cylindrical sleeve due to friction. Then, the knob is turned, which drives the pressing rod I to rotate, thereby driving the cylindrical gear I to rotate, which in turn drives the cylindrical gear II, belt and pulley to rotate, thereby driving the pressing rod II to rotate, thus causing the pressing rod I and pressing rod II to clamp the tamping tool rod. The inner side of the arc-shaped plate of pressing rod I and pressing rod II is equipped with protective strips, which increases the friction with the tamping tool rod, thereby preventing the tamping tool rod from falling off.

[0023] This invention utilizes two electric cylinders, which drive a large pushing block to move, which in turn moves a cylindrical limiting shaft along a limiting groove. When the limiting groove reaches its end, the large pushing block continues to move as the electric cylinders move it. The large pushing block then rotates downwards around the cylindrical limiting shaft, causing the cylindrical shaft to move along the limiting frame. This causes the insert block, the first tamping pick, and the second tamping pick to first move laterally and then rotate around the cylindrical limiting shaft. This allows the tamping rods on the first and second tamping picks to synchronously converge the ballast inwards. Simultaneously, a small vibrator is used to vibrate the square support plate, which in turn vibrates the cylindrical gear I, the extrusion rod I, the cylindrical gear II, the extrusion rod II, and the cylindrical sleeve. This, in turn, vibrates the tamping rods, thereby compacting the ballast and enhancing the stability and density of the track. Attached Figure Description

[0037] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model patent. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0038] In the description of this utility model, it should be noted that the terms "upper," "lower," "front," "rear," "left," and "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are merely simplified descriptions for ease of description and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model patent. Furthermore, for ease of description, spatial relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatial relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the accompanying drawings. The device may have other orientations (rotated 90 degrees or in other orientations), and the spatial relative descriptive terms used herein can be interpreted accordingly.

[0039] Implementation, for example Figures 1-12As shown, a tamping pick for a small railway tamping machine includes: a first tamping pick part 1, an external connecting part 2, and a second tamping pick part 3;

[0040] The structure of the first tamping part 1 is exactly the same as that of the external part 2. The external part 2 is located between the first tamping part 1 and the second tamping part 3. The external part 2 and the first tamping part 1 are intermittently connected with the second tamping part 3. Controllers are fixedly installed on the first tamping part 1, the external part 2 and the second tamping part 3. Signals are received through the signal processor in the controller, and the electrical components of the equipment are controlled to operate in an orderly manner through the central processing unit in the controller. The first tamping part 1 and the second tamping part 3 can be connected by the external part 2, or the first tamping part 1 or the second tamping part 3 can be used alone.

[0041] In one optional embodiment of this utility model, such as Figures 4-6 As shown, the first tamping pick part 1 includes: a hand grip 101, a connecting frame 102, a small vibrator 103, an outer plate 104, a knob 105, and a square block 117;

[0042] The handgrip 101 is fixedly connected to the connecting frame 102. A person holds the handgrip 101 to grasp the first tamping pick 1, facilitating the tamping of the ballast under the railway sleepers to enhance track stability and compaction. A square block 117 is connected to each side of the connecting frame 102. Each square block 117 has a square groove, the size of which is the same as that of the rectangular block 115. One side of each square block 117 has a locking slot, which intermittently engages with a plug 206 of an external part 2. Small vibration... The vibrator 103 is fixedly connected to the connecting frame 102, and the output shaft of the small vibrator 103 is connected to the square support plate 110; the outer plate 104 is fixedly connected to the connecting frame 102; the knob 105 passes through the hole of the outer plate 104 and is fixedly connected to the shaft of the extrusion rod I 107. The diameter of the hole on the outer plate 104 is larger than the diameter of the knob 105 shaft. In this way, when the small vibrator 103 drives the square support plate 110 to vibrate, and then drives the knob 105 to vibrate, the knob 105 will not have too much contact with the outer plate 104, which will reduce the service life of the knob 105.

[0043] In one optional embodiment of this utility model, such as Figure 8 As shown, the first tamping pick part 1 also includes: cylindrical gear I 106, pressing rod I 107, cylindrical gear II 108, pressing rod II 109, square support plate 110 and cylindrical sleeve 111;

[0044] The extrusion rod I 107 is rotatably mounted on the square support plate 110. The extrusion rod I 107 is fixedly connected to the cylindrical gear I 106, which is also rotatably mounted on the square support plate 110. The cylindrical gear I 106 meshes with the cylindrical gear II 108, which is rotatably mounted on the square support plate 110. The cylindrical gear II 108 is connected to the pulley and extrusion rod II 109 via a belt. The extrusion rod II 109 is rotatably mounted on the square support plate 110. A cylindrical sleeve 111 is fixedly mounted on the square support plate 110. The inner diameter of the cylindrical sleeve 111 is the same as the size of the upper cylindrical end of the tamping rod 112, and a protective strip is provided on the inner side of the cylindrical sleeve 111. Specifically, the tamping rod 112 is manually inserted into the cylindrical sleeve 111. Since the inner diameter of the cylindrical sleeve 111 is the same as the size of the upper cylinder of the tamping rod 112, and the inner side of the cylindrical sleeve 111 is provided with anti-slip strips, the tamping rod 112 will not easily fall off after being inserted into the cylindrical sleeve 111 due to friction. Then, the knob 105 is turned, which drives the extrusion rod I 107 to rotate, which in turn drives the cylindrical gear I 106 to rotate, which further drives the cylindrical gear II 108, belt and pulley to rotate, which in turn drives the extrusion rod II 109 to rotate, thus causing the extrusion rod I 107 and extrusion rod II 109 to clamp the tamping rod 112. The inner side of the arc plate of the extrusion rod I 107 and extrusion rod II 109 is provided with protective strips, which increases the friction with the tamping rod 112, thereby preventing the tamping rod 112 from falling off.

[0045] In one optional embodiment of this utility model, such as Figure 8 As shown, the extrusion rods I 107 and II 109 of the first tamping part 1 have the same structure. An arc-shaped plate is fixedly installed on both extrusion rods I 107 and II 109. The inner diameter of the arc-shaped plate is the same as the size of the cylinder at the upper end of the tamping rod 112. Anti-slip strips are provided on the inner side of the arc-shaped plates of extrusion rods I 107 and II 109. The anti-slip strips can effectively prevent the tamping rod 112 from detaching.

[0046] In one optional embodiment of this utility model, such as Figure 4 As shown, the first tamping pick part 1 also includes: tamping pick rod 112;

[0047] The tamping rod 112 is inserted into the cylindrical sleeve 111 and can be removed, which facilitates manual replacement and maintenance of the tamping rod 112. The tamping rod 112 is mainly used in small railway tamping machines. This product improves its service life and reduces the frequency of replacement by machining and brazing hard alloy, thereby reducing costs.

[0048] In one optional embodiment of this utility model, such as Figure 9As shown, the first tamping pick part 1 also includes: a lead screw moving mechanism 113, a slider 114, a rectangular block 115 and a handwheel 116;

[0049] The frame of the lead screw moving mechanism 113 is fixedly connected to one of the square blocks 117. The shaft of the lead screw of the lead screw moving mechanism 113 is fixedly connected to the handwheel 116. The screw threads of the lead screw moving mechanism 113 rotate in opposite directions. The threads at both ends of the lead screw moving mechanism 113 are threadedly engaged with a slider 114. Each slider 114 is slidably mounted on the bracket of the lead screw moving mechanism 113. A rectangular block 115 is fixedly mounted on the inner side of each slider 114. Each slider 114 has a protrusion on its inner side, which increases friction. Specifically, after the insert 206 is inserted into the side of the square block 117, the handwheel 116 is manually rotated, which drives the lead screw moving mechanism 113 to move the two sliders 114 inward, so that the two rectangular blocks 115 are inserted into the square grooves of the insert 206 and the square block 117, thereby effectively preventing the insert 206 and the square block 117 from separating.

[0050] In one optional embodiment of this utility model, such as Figures 10-12 As shown, the external part 2 includes: a connecting frame 201, a handle 202, an electric cylinder 203, a limiting groove 209, and a side connecting mechanism;

[0051] A handle 202 is fixedly installed on the connecting frame 201; there are two electric cylinders 203, the cylinder bodies of the two electric cylinders 203 are respectively connected to the connecting frame 201 through movable connecting parts, and the telescopic rod end of each electric cylinder 203 is rotatably connected to the foot of the large push block 204 of a side connecting mechanism on the same side; the connecting frame 201 is provided with two limiting grooves 209, each limiting groove 209 is respectively connected to the cylindrical limiting shaft 208 of a side connecting mechanism on the same side; there are two sets of side connecting mechanisms, and the two sets of side connecting mechanisms are respectively installed on the connecting frame 201, and the two sets of side connecting mechanisms are symmetrically distributed.

[0052] In one optional embodiment of this utility model, such as Figures 10-12 As shown, the side connection mechanism of the external part 2 includes: a large push block 204, a limiting frame 205, an insert block 206, a cylindrical shaft 207, and a cylindrical limiting shaft 208;

[0053] The large pushing block 204 is equipped with a foot, which is rotatably connected to the telescopic rod end of the electric cylinder 203. A cylindrical limiting shaft 208 is fixedly installed on the large pushing block 204, and the cylindrical limiting shaft 208 cooperates with the limiting groove 209. The insert block 206 is fixedly connected to the large pushing block 204, and the insert block 206 is equipped with a square groove, which intermittently cooperates with the rectangular block 115. There are two limiting frames 205, and each limiting frame 205 is attached to a predetermined position of the connecting frame 201 by a fastening mechanism. In the installation area, each limit frame 205 has a cylindrical shaft 207 slidably installed in its groove. There are two cylindrical shafts 207, which are fixedly installed on both sides of the insert block 206. Specifically, when the first tamping pick part 1 and the second tamping pick part 3 need to be used simultaneously, the handle 202 is manually grasped to lift the outer part 2, thereby inserting the insert block 206 into one of the square blocks 117. The second tamping pick part 3 is connected to the outer part 2 in the same way. Now, the first tamping pick part 1, the outer part 2, and the second tamping pick part 3 are connected as one unit. Then, by manually holding the connecting frame 201, the tamping pick rod 112 is inserted into the ballast to be worked on. Next, the two electric cylinders 203 are activated, causing the electric cylinders 203 to move the large pushing block 204, which in turn moves the cylindrical limiting shaft 208 along the limiting groove 209. When the limiting groove 209 moves to its end, as the electric cylinders 203 continue to move the large pushing block 204, the large pushing... The moving block 204 will rotate downwards around the cylindrical limiting shaft 208, thereby driving the cylindrical shaft 207 to move along the limiting frame 205. This will cause the insert block 206, the first tamping pick part 1, and the second tamping pick part 3 to first move to both sides and then rotate around the cylindrical limiting shaft 208. This will enable the tamping rods 112 on the first tamping pick part 1 and the second tamping pick part 3 to synchronously gather the ballast inwards. At the same time, the small vibrator 103 will be used to compact the ballast, enhancing the stability and density of the track.

[0054] Working principle:

[0055] This equipment can be used independently of the first tamping pick section 1 or the second tamping pick section 3, or it can be combined with the first tamping pick section 1 and the second tamping pick section 3 through the external part 2, so that the first tamping pick section 1 and the second tamping pick section 3 can work simultaneously, improving work efficiency. The tamping pick rod 112 of this equipment is machined and brazed with hard alloy to improve the service life of the product and reduce the replacement frequency, thereby reducing costs. The first tamping pick section 1 and the second tamping pick section 3 of this equipment have a simple structure, are easy to use, and have low manufacturing costs.

[0056] The first tamping pick part 1 and the second tamping pick part 3 can be used independently. When using either the first tamping pick part 1 or the second tamping pick part 3 independently, the tamping pick rod 112 is first manually inserted into the cylindrical sleeve 111. Since the inner diameter of the cylindrical sleeve 111 is the same as the size of the upper cylinder of the tamping pick rod 112, and the inner side of the cylindrical sleeve 111 is provided with anti-slip strips, the tamping pick rod 112 will not easily fall out after being inserted into the cylindrical sleeve 111 due to friction. Then, turning knob 105 rotates the extrusion rod I 107, which in turn rotates the cylindrical gear I 106, which in turn rotates the cylindrical gear II 108, the belt, and the pulley, thus rotating the extrusion rod II 109. This causes the extrusion rods I 107 and II 109 to clamp the tamping rod 112. Protective strips are provided on the inner sides of the arc-shaped plates of both extrusion rods I 107 and II 109, increasing the friction with the tamping rod 112 and preventing it from falling off.

[0057] By manually holding the hand grip 101, one can pick up either the first tamping pick part 1 or the second tamping pick part 3, and then insert the tamping pick rod 112 into the ballast. The small vibrator 103 is then activated, which causes the small vibrator 103 to drive the square support plate 110 to vibrate, thereby driving the cylindrical gear I 106, the extrusion rod I 107, the cylindrical gear II 108, the extrusion rod II 109 and the cylindrical sleeve 111 to vibrate, which in turn drives the tamping pick rod 112 to vibrate, thereby compacting the ballast.

[0058] When the first tamping pick part 1 and the second tamping pick part 3 need to be used simultaneously, the handle 202 is manually held to lift the outer part 2, so that the insert 206 is inserted into one of the square blocks 117. After the insert 206 is inserted into the side of the square block 117, the handwheel 116 is manually turned, which drives the lead screw moving mechanism 113 to move the two sliders 114 inward, so that the two rectangular blocks 115 are inserted into the square grooves of the insert 206 and the square block 117, thereby effectively preventing the insert 206 and the square block 117 from separating. In the same way, the second tamping pick part 3 is connected to the outer part 2. At this time, the first tamping pick part 1, the outer part 2 and the second tamping pick part 3 are connected as one unit.

[0059] Subsequently, by manually holding the connecting frame 201, the tamping rod 112 is inserted into the ballast to be worked on. Then, the two electric cylinders 203 are activated, which in turn move the large pushing block 204, thereby moving the cylindrical limiting shaft 208 along the limiting groove 209. When the limiting groove 209 reaches its end, as the electric cylinder 203 continues to move the large pushing block 204, the large pushing block 204 will rotate downwards around the cylindrical limiting shaft 208, thereby moving the cylindrical shaft 207 along the limiting frame 205, and thus moving the insert block 206 and the first The tamping pick section 1 and the second tamping pick section 3 first move to both sides and then rotate around the cylindrical limiting shaft 208 as the center. This allows the tamping pick rods 112 on the first tamping pick section 1 and the second tamping pick section 3 to synchronously gather the ballast inward. At the same time, in conjunction with the small vibrator 103, the small vibrator 103 drives the square support plate 110 to vibrate, thereby driving the cylindrical gear I 106, the extrusion rod I 107, the cylindrical gear II 108, the extrusion rod II 109 and the cylindrical sleeve 111 to vibrate, which in turn drives the tamping pick rod 112 to vibrate, thereby compacting the ballast and enhancing the stability and density of the track.
