Description

Technical Field

[0001] This utility model belongs to the field of railways, and in particular relates to a precision measuring device for railway continuous beams. Background Technology

[0002] In railway construction, beam bridges are often used when it is necessary to cross rivers, roads or structures. Continuous beams are a commonly used bridge structure. In order to ensure the safety of railway operation, it is necessary to measure the levelness of continuous beams. The existing levelness measurement uses a spirit level, but the measurement accuracy of the spirit level is relatively low. Utility Model Content

[0003] The purpose of this invention is to provide a precision measuring device for railway continuous beams to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A precision measuring device for a continuous railway beam includes a guide rod, a base, clamping blocks, a column, a horizontal plate, a vertical plate, markers, a ring, and a level. The guide rod is fixed to the continuous beam with screws. A slidingly connected base is provided at the guide rod. Two integrally formed clamping blocks are provided on both sides of the lower part of the base. The space between the two clamping blocks can connect with the guide rod. A column with screws is provided on the base. A ring is fitted on the column. A horizontal plate with screws is provided on one side of the ring. A vertical plate with screws is provided behind the horizontal plate. The vertical plate has an inverted L-shaped design. Multiple markers are provided on the horizontal plate. A level is embedded in the base.

[0006] Preferably, the horizontal plate has a circular hole for installing the marker. The marker can move up and down in the vertical direction. A positioning ring is provided below the circular ring and is sleeved on the column. The positioning ring is limited by a positioning screw. The circular ring is connected to the positioning ring by a bearing. A balloon is attached to the upper part of the vertical plate. The balloon is located above the circular hole and is set in a one-to-one correspondence with the marker.

[0007] Preferably, the marker includes an upper conical rod, a connecting rod, and a marker rod. The top of the upper conical rod is provided with a screw-mounted needle, the distance between the needle and the balloon is one centimeter. The upper conical rod is threadedly connected to the connecting rod and to a circular hole. A spring is sleeved on the upper conical rod above the circular hole, and the end of the spring is connected to a crossbar. The spring can be compressed to a maximum of one centimeter. The connecting rod is threadedly connected to the marker rod. The marker rod adopts a ballpoint pen refill design and is filled with a red marking liquid. The red liquid inside the marker rod can flow out through the ball at the bottom of the marker rod.

[0008] Compared with the prior art, this utility model has the following advantages: The design is reasonable; the level bubble on the base allows for constant observation of the base's level, and the base's movement along the guide rod enables rapid measurement of continuous beams over a longer range, improving measurement efficiency; the horizontal plate is connected to the ring, allowing the horizontal plate to rotate under the ring's influence to adapt to different angle measurement requirements; the ring's height is adjusted under the positioning ring to accommodate continuous beams of varying thicknesses; during measurement, the base moves along the guide rod, and the bottom of the marker rod on the horizontal plate contacts the connecting beam. A marking operation is performed using the marker rod. If the continuous beam has a depression greater than one centimeter, the marker rod separates from the continuous beam and cannot be marked; the unmarked area is the depression. If the continuous beam has a protrusion greater than one centimeter, the marker rod, connecting rod, and upper conical rod are pushed upwards, causing the needle on the upper conical rod to puncture the balloon, alerting the user to the protrusion. The use of marking and the balloon improves measurement accuracy. Attached Figure Description

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0012] like Figures 1-2As shown, a precision measuring device for a continuous railway beam includes a guide rod 1, a base 2, clamping blocks 3, a column 4, a horizontal plate 5, a vertical plate 6, a marker 7, a circular ring 8, and a spirit level 9. The guide rod 1 is fixed to the continuous beam with screws, ensuring its flatness during installation. The base 2 is slidably connected to the guide rod 1, and the lower two sides of the base 2 are provided with integrally formed clamping blocks 3. The space between the two clamping blocks 3 can connect with the guide rod 1. The column 4 is screw-mounted on the base 2, and a circular ring 8 is sleeved on the column 4. Ring 8 has a horizontal plate 5 mounted with screws on one side, and a vertical plate 6 mounted with screws behind the horizontal plate 5. The vertical plate 6 is designed in an inverted L shape. Multiple markers 7 are provided on the horizontal plate 5. A horizontal bubble 9 is embedded in the base 2. A circular hole 10 is provided on the horizontal plate 5 for mounting the markers 7. The markers 7 can move up and down vertically. A positioning ring 11 is provided below the ring 8, and the positioning ring 11 is fitted onto the column 4. The positioning ring 11 is limited by positioning screws 12. The ring 8 is connected to a bearing... The positioning ring 11 is connected, and the ring and horizontal plate can rotate along the column under manual operation. Lubricant can be applied inside the ring. When rotation is not required, the ring is positioned using a pin. A balloon 13 is attached to the upper part of the vertical plate 6. The balloon 13 is located above the circular hole 10, and the balloon 13 is set one-to-one with the marker 7. The marker 7 includes an upper conical rod 17, a connecting rod 14, and a marker rod 15. The top of the upper conical rod 17 is equipped with a screw-mounted needle. The distance between the needle and the balloon 13 is one centimeter. The upper conical rod 17 and the connecting rod 15 are connected. The connecting rod 14 is threaded and can be replaced with a suitable length as needed. The upper tapered rod 17 is connected to the round hole 10. A spring 16 is sleeved on the upper tapered rod 17 above the round hole 10. The end of the spring 16 is connected to the crossbar 5. The spring 16 can be compressed to a maximum of one centimeter. The connecting rod 14 is threaded to the marking rod 15. The marking rod 15 adopts a ballpoint pen refill design. The marking rod 15 is filled with red marking liquid. The red liquid in the marking rod 15 can flow out through the ball below the marking rod 15.

[0013] The working principle of this utility model is as follows: First, select a guide rod 1 of appropriate length according to the continuous beam to be measured, and fix the guide rod in the middle position of the continuous beam to be measured. Install the base 2 on the guide rod using the locking block 3. Manually adjust the height of the positioning ring 11 according to the condition of the continuous beam to be measured. The height of the positioning ring is determined by the height of the ring 8 and the horizontal plate 5. First, move the horizontal plate 5 to one side of the column 4. Select a connecting rod 14 of appropriate length according to the situation, so that the marking rod 15 contacts the top of the continuous beam. Manually drive the base to move at a constant speed along the guide rod. During the movement, the marking rod performs a marking operation. If the continuous beam has a depression greater than one centimeter, the spring will be compressed to its maximum and the marker pole will not descend, thus separating the marker pole from the continuous beam and preventing marking. The unmarked area is the depression, reminding people that it is a depression. If the continuous beam has a protrusion greater than one centimeter, the marker pole, connecting pole, and upper conical pole 17 will be pushed upward, causing the needle at the upper conical pole to puncture the balloon 13, reminding people that it is a protrusion. After the balloon is punctured, personnel need to add balloons in time. After the measurement on one side of the column is completed, the ring can be manually rotated to move the horizontal plate to the other side for the next measurement operation.

[0014] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
