Therefore, in order to prevent the spring strips from breaking and failing to influence the driving safety, related units are required to be responsible for maintenance, maintenance and management of railway engineering equipment, and the engineering departments can regularly and comprehensively check the spring strips and replace the failed spring strips. At present, in the actual work equipment inspection, methods such as manual knocking inspection and fastener trolley system inspection are provided for an inspection mode of a spring strip, wherein the manual inspection is mainly used, an operator needs to use an inspection hammer to knock and inspect the spring strip fastener, the working time is usually arranged in a skylight point of 0: 30-4: 30, the time is late, the environment is poor, and the inspection work of the elastic fastener is directly related to the safety problem of line operation, so that the operator urgently needs an inspection tool with high efficiency and low working strength for the inspection work of the spring strip equipment of the fastener system, so as to ensure that the equipment state of the fastener system is good and the safety of a high-speed train is ensured.

The inspection hammer that present an alignment operation personnel allocated and used, tup both sides are pyramid and cylinder respectively, for making whole weight reduce as far as possible, so under the condition that satisfies the hammer handle tenon structure, tup both sides all are thinner and the tip area is less, more are suitable for relevant operations such as train detection. The contact surface of the tip of the inspection hammer for knocking is small, so that the problems of knocking failure and inaccurate knocking can be caused in the knocking inspection of the elastic strip, and whether the elastic strip fails or not can be judged more difficultly through the sound generated by knocking. Night sight is bad in the skylight point in addition, originally, the work that only needs to strike often will strike 2 times in the reality and even 3 times just can make the judgement, the artifical waste of unnecessary has been caused, greatly reduced the bullet strip and hit the efficiency of inspection, the working strength of operation personnel has also been aggravated simultaneously, if for example if two strands of circuit fasteners about inspection 200 meters now, it is about 1300 more to need to examine the bullet strip altogether, operation personnel uses present inspection hammer, need strike repeatedly, working strength is very big.

When the multifunctional inspection hammer is used, an operator can hold the multifunctional inspection hammer to detect the elastic strip without stooping, meanwhile, due to the large knocking surface of the trapezoidal hammer, knocking and reverberation are stable, the detection efficiency is guaranteed, whether the minimum rail gap of a common structure rail gap and a steel rail insulating joint is exceeded or not can be quickly measured by using the knocking head, field data measurement with low precision can also be carried out by using the inspection hammer, the use of the operator is greatly facilitated, and the carrying amount of tools of the operator is reduced.

Taking a station track of a certain station of Daxi high-speed railway as an example, the total length of the track is 934 m. The existing work inspection hammer is used for carrying out elastic strip knocking inspection operation, 3 persons are required to operate in a skylight for 3 hours and 40 minutes, and the operating personnel reflect high working strength after operation; the same workload is completed by using the inspection hammer, only 2 persons are required to operate for 2 hours and 30 minutes in a day window point, and the working intensity of operators is obviously reduced after operation. According to the regulation of related documents and the conventional labor cost, the inspection period of the fastener system is 1 time per half year, each person in a Daxi sky window has 200 yuan of labor cost, and the length of the Daxi high-speed rail is managed by 1049.278 km. Accordingly, the project benefit is roughly estimated, and the calculation formula is as follows:

hammer efficiency is checked using existing work: 0.934 ÷ 3 ÷ 3.667=0.08km/h

Use the multi-functional inspection hammer efficiency of this application: 0.934 ÷ 2 ÷ 2.5=1.18km/h

The number of skylights required for fastener system inspection is completed periodically: 1049.278 ÷ 0.08 ÷ 4 ≈ 3278

1049.278 ÷ 1.18 ÷ 4 ≈ 222 pieces

Only the number of skylights is saved by the fastener system inspection project: 3278 and 222=3056

And (3) saving expenditure: 200 × 3056=611200 yuan.
