Description

Technical Field

[0001] The utility model relates to the technical field of railway inspection, in particular to a high-strength inspection hammer with a rapid change function. Background Art

[0002] In modern railway construction, the inspection of line equipment should adhere to the principle of "combining dynamic and static inspections, and paying equal attention to structural and geometric dimension inspections". The inspection hammer is one of the important inspection tools in the structural inspection of engineering equipment. The inspection hammer is mainly used to inspect the torque of connecting rods and key bolts of line equipment. It only needs to knock to identify whether they are loose;

[0003] At present, the inspection hammer consists of two parts: a hammer head and a handle, which makes its function too single and is only suitable for checking the status of rails and connecting parts. The daily inspection work in the line workshop inspection area also needs to undertake some minor repair work of spare parts. In addition, the inspection area is less staffed and requires more tools and machinery, resulting in low labor efficiency of workers. Therefore, it is urgent to develop a multifunctional inspection hammer to reduce the number of tools and labor input. Utility Model Content

[0004] The utility model aims to provide a high-strength inspection hammer with a quick-change function to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-strength inspection hammer with a quick-change function, comprising: a hammer head, a re-tightening structure, a connecting structure, an adjustment structure and a measuring structure; the re-tightening structure is arranged on the outer wall of the hammer head, and the re-tightening structure comprises a horizontal connecting head welded on the outer wall of the hammer head, a sleeve plugged into the horizontal connecting head and a vertical connecting head welded on the outer wall on the other side of the hammer head; the connecting structure is plugged into the inside of the hammer head, and the connecting structure has a plug plugged into the inside of the hammer head, and a hammer arm is welded on one side of the plug; the adjustment structure is arranged at one end of the connecting structure, and the adjustment structure comprises a connecting strip pressed on the outer wall of one end of the hammer arm, a long hole opened on the outer wall of the connecting strip, a third fastener plugged in the long hole and an adjustment arm inserted on the outer wall of the third fastener; the measuring structure is arranged on the outer wall of one side of the hammer head, and the measuring structure has a measuring hammer arranged on the outer wall of one side of the hammer head.

[0006] By adopting the above technical solution, the bolt can be knocked through the sleeve to see if it is loose, and the horizontal connector, vertical connector, sleeve, hammer arm, connecting strip and adjustment arm can be adjusted between the straight handle wrench and the T-wrench to cope with the work of re-tightening the joint bolts and the upturned bolts. The measuring hammer can be used to measure the gap between the rails. The device can quickly switch between the functions of measuring the gap, detecting the tightening of the bolts and re-tightening the bolts. The integration of multiple functions can reduce the investment in detection and repair personnel and the number of tools, thereby improving the work efficiency of track maintenance.

[0007] Preferably, the re-tightening structure also includes a first through hole opened on the outer wall of the sleeve and a first pin sequentially plugged into the first hole and the horizontal connector, and the horizontal connector and the vertical connector are in a relatively vertical state on the hammer head.

[0008] By adopting the above technical solution, the sleeve is connected by inserting the first pin in two directions of the hammer head. By installing the sleeve on the horizontal connecting head, the bolts in the horizontal direction of the track can be re-tightened. By installing the sleeve on the vertical connecting head, the upward bolts fixing the track can be re-tightened, thereby realizing the role of multiple re-tightening functions of one device.

[0009] Preferably, the connection structure further includes a plug hole opened inside the hammer head and a first fastener connecting the hammer head to the plug.

[0010] By adopting the above technical solution, the hammer head and the hammer arm can be connected by using a first fastener of a long bolt and a nut, so that the two parts can be disassembled. When damage occurs during frequent use, the parts can be disassembled and replaced to ensure that the device can be repaired by replacing parts and prolonging its service life.

[0011] Preferably, the adjustment structure also includes a connecting hole opened at one end of the hammer arm, a second socket opened on the outer wall of the hammer arm and the adjustment arm, a second fastener connecting the connecting strip to the hammer arm, a third fastener connected to the long hole at one end of the adjusting arm of the connecting strip, and a second pin inserted into the second socket at a position between the second fastener and the third fastener.

[0012] By adopting the above technical solution, by adjusting the adjusting arm to be in the same straight line with the hammer arm, and plugging the second pin into the corresponding second socket and the long hole, the device can form a straight-handled wrench to re-tighten the joint bolts, pull out the second pin, pull the adjusting arm backward and rotate it ninety degrees on the third fastener, so as to form a T-wrench to re-tighten the skyward bolts. This function eliminates the need to carry straight-handled wrenches, T-wrenches and other tools for daily inspections, and can realize immediate discovery and immediate rectification, thereby improving the utilization rate of the skylight and operating efficiency.

[0013] Preferably, the measuring structure further comprises a threaded head welded on the outer wall of the hammer head and a numerical slot provided on the outer wall of the measuring hammer, and a threaded hole is provided at the bottom of the measuring hammer and is threadedly connected to the threaded head.

[0014] By adopting the above technical solution, the measuring hammer with threaded connection can be easily installed and disassembled. If the accuracy decreases due to wear of the outer wall after long-term use, the worn measuring hammer can be unscrewed and replaced to ensure that the size of the track gap can be accurately measured using the scale in the numerical slot.

[0015] Preferably, the main body of the measuring hammer is formed by a conical structure, and the outer wall of the numerical groove is laser engraved with diameter values ​​ranging from two millimeters to twenty millimeters, and red marking lines are drawn at the positions of six millimeters and eighteen millimeters.

[0016] By adopting the above technical solution, by using laser engraving technology to engrave integer values ​​of diameter from two millimeters to twenty millimeters at corresponding positions, the track gap value can be measured by inserting the pointed tip between the two rails at the joint, and marking the six millimeter and eighteen millimeter scale lines with red lines, which is convenient for intuitively reflecting whether the track gap meets the requirements.

[0017] Preferably, the horizontal connecting head is in a vertical state relative to the hammer arm, the vertical connecting head and the hammer arm are on the same axis, and the sleeve is equipped with three groups of models with different apertures, and the three groups of apertures are 22 mm, 24 mm and 32 mm respectively.

[0018] By adopting the above technical solution, through setting the positions of the horizontal connector, the vertical connector and the hammer arm, assembling the sleeves at different positions can form wrenches with different functions to meet the needs of different re-tightening operations. At the same time, sleeves with different apertures can be used for re-tightening operations on different types of bolts, avoiding the need to carry various wrenches of different sizes for inspection operations.

[0019] Preferably, the hammer arm, the adjustment arm and the connecting strip are all made of magnesium-aluminum alloy, and the outer walls of the hammer arm and the adjustment arm are sleeved with rubber skin.

[0020] By adopting the above technical solution, the original wooden material of the handle of the device is replaced with a magnesium alloy material by utilizing the characteristics of the magnesium-aluminum alloy material, such as low density, high strength, large elastic modulus, good heat dissipation, good shock absorption, greater impact load bearing capacity than aluminum alloy, and good resistance to corrosion by organic matter and alkali. In addition to ensuring the strength required for the re-tightening parts, the original lightness of the device is retained, and the friction when the re-tightening bolts of the device are held can be increased by applying a rubber skin.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] (1) The bolts can be tapped to check if they are loose through the sleeve. The horizontal connector, vertical connector, sleeve, hammer arm, connecting strip and adjustment arm can be adjusted between the straight handle wrench and the T-wrench to cope with the work of re-tightening the joint bolts and the overhead bolts. The measuring hammer can be used to measure the gap between the rails. The device can quickly switch between the functions of measuring the gap, detecting the tightening of the bolts and re-tightening the bolts. The integration of multiple functions can reduce the number of inspection and repair personnel and the number of tools, thereby improving the efficiency of track maintenance;

[0023] (2) By using laser engraving technology to engrave integer values ​​of diameters from 2 mm to 20 mm in the corresponding numerical slots, the tip of the measuring hammer can be inserted between the two rails at the joint to measure the rail gap value. The 4 mm and 20 mm scale lines are marked with red lines to intuitively reflect whether the rail gap meets the requirements. This structure adds the rail gap measurement function, so that daily inspections no longer require carrying a rail gap measuring ruler. The device can be used directly to meet the needs of measuring rail gaps during anti-expansion and anti-break periods, reducing the number of tools and equipment to be carried. The form is easy to read and easy to operate, optimizes the working method, and improves labor efficiency;

[0024] (3) By taking advantage of the characteristics of magnesium-aluminum alloy, such as low density, high strength, large elastic modulus, good heat dissipation, good shock absorption, greater impact load bearing capacity than aluminum alloy, and good resistance to corrosion by organic matter and alkali, the original wooden material of the device handle is replaced with magnesium alloy. In addition to ensuring the strength required for the tightening parts, the original lightness of the device is retained, the bending strength of the device is enhanced, and the risk of breakage and deformation of the hammer arm, adjustment arm and connecting strip is reduced.

[0038] Embodiment 3

[0039] See also Figures 1 to 5The main body of the measuring hammer 502 is formed by a conical structure. The outer wall of the numerical groove 503 is laser engraved with diameter values ​​ranging from two millimeters to twenty millimeters. The laser engraving technology is used to engrave the diameter integer values ​​from two millimeters to twenty millimeters at the corresponding positions. The rail gap value can be measured by inserting the pointed tip between the two rails at the joint, and red marking lines are drawn at the positions of six millimeters and eighteen millimeters.
