Description

Technical Field

[0001] This utility model relates to the field of power trowels, specifically a power trowel for road construction. Background Technology

[0002] A power trowel, also known as a finishing machine, has a main structure consisting of a gasoline engine-driven trowel rotor. A trowel is mounted on the bottom of a cross-shaped structure in the middle of the rotor. The trowel is tilted in the same direction as the rotor's rotation. The gasoline engine drives a V-belt to rotate the trowel rotor. To operate it, first start the engine, then hold the control handles. Pushing both handles forward together moves the machine forward, and pulling them back together moves the machine backward.

[0003] In existing technology, when using a power trowel, the operator mainly moves the machine by holding the handle. However, holding the handle for a long time can easily cause hand fatigue, and some people's palms are also prone to sweating and becoming slippery, which can cause the operator's hand to slip off the handle, causing the power trowel to rotate and potentially injure people nearby. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as hand fatigue from prolonged gripping and exertion, and the slippery nature of some workers' palms due to sweat, which can cause their hands to slip off the handles and the power trowel to spin, potentially injuring those nearby, this invention proposes a power trowel for road construction.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a power trowel for road construction, including a power trowel, wherein the surface of the power trowel is provided with an anti-hand slip mechanism;

[0006] The anti-slip mechanism includes a rope, one side of which is fixedly connected to the surface of a power polisher. A fixing block is fixedly connected to one side of the rope, and a first semi-ring block is fixedly connected to one side of the fixing block. A T-shaped groove and a second hollow groove are formed on the surface of the fixing block. A connecting block is slidably connected to the inner cavity of the T-shaped groove. A second semi-ring block is fixedly connected to one side of the connecting block, and a rack is fixedly connected to the other side of the connecting block. A first hollow groove is formed in the inner cavity of the fixing block, and a gear is rotatably connected to the inner cavity of the first hollow groove. The teeth of the gear mesh with the teeth of the rack. A rotating block is rotatably connected to the inner cavity of the second hollow groove. One side of the rotating block is fixedly connected to one side of the gear, and a ratchet is fixedly connected to the surface of the rotating block. A first fixing rod and a second fixing rod are fixedly connected to one side of the fixing block. A pawl is rotatably connected to the surface of the first fixing rod, and the teeth of the pawl mesh with the teeth of the ratchet. An elastic plate is provided on the surface of the pawl, and the top of the elastic plate is fixedly connected to the bottom of the second fixing rod.

[0007] Preferably, a support block is fixedly connected to the inner cavity of the T-shaped groove, a spring is fixedly connected to the bottom of the support block, and the bottom of the spring is fixedly connected to the top of the connecting block.

[0008] Preferably, a fixing plate is fixedly connected to the surface of the pawl, and the fixing plate is L-shaped.

[0009] Preferably, a limiting ring block is provided on one side of the pawl, and the inner cavity of the limiting ring block is fixedly connected to the surface of the first fixing rod.

[0010] Preferably, a pressure block is fixedly connected to one side of the fixing block, and a push block is fixedly connected to the bottom of the rack.

[0011] Preferably, a reinforcing block is fixedly connected to the surface of the first semi-ring block, and one side of the reinforcing block is fixedly connected to one side of the fixing block.

[0012] Preferably, a first sponge block is fixedly connected to the inner cavity of the first semi-ring block, and a second sponge block is fixedly connected to the inner cavity of the second semi-ring block.

[0013] The advantages of this utility model are:

[0014] This invention involves passing a hand through the first and second semi-ring blocks, then moving the second semi-ring block upwards. The second semi-ring block, via a connecting block, moves a rack, which in turn drives a gear and ratchet to rotate. The ratchet then presses against a pawl, causing it to rotate. The pawl, through the ratchet, limits the gear's rotation, ensuring it can only rotate in one direction. This prevents the rack and second semi-ring blocks from moving backwards, thus securing the first and second semi-ring blocks stably around the wrist. The operator can then hold the handle of the power trowel to operate it. During use, the worker can... When the operator's hand becomes sore or sweaty and detaches from the handle of the polishing machine, the first and second half-ring blocks, along with the rope, can still effectively connect the polishing machine to the wrist, preventing the polishing machine from spinning out of control. Furthermore, the mobility of the second half-ring block allows it to be used by people with wrists of different sizes, broadening its applicability. This solves the problem of hand soreness caused by prolonged gripping and exertion, and addresses the issue of sweaty, slippery palms that can cause the operator's hand to slip off the handle, leading to the polishing machine spinning and potentially injuring those nearby.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a power trowel for road construction. (Refer to...) Figure 1-5A road construction power trowel includes a power trowel 1, the surface of which is provided with an anti-hand slip mechanism 2. The power trowel 1 can be used to smooth the road under construction, making the road smoother. The anti-hand slip mechanism 2 is fixed to the handle of the power trowel 1, which can reinforce the worker's hand and make it difficult for the arm to separate from the power trowel 1.

[0025] The anti-slip mechanism 2 includes a rope 201. One side of the rope 201 is fixedly connected to the surface of the polishing machine 1. A fixing block 202 is fixedly connected to one side of the rope 201. A first semi-ring block 203 is fixedly connected to one side of the fixing block 202. A T-shaped groove 205 and a second hollow groove 210 are formed on the surface of the fixing block 202. A connecting block 206 is slidably connected to the inner cavity of the T-shaped groove 205. A second semi-ring block 204 is fixedly connected to one side of the connecting block 206. A rack 207 is fixedly connected to the other side of the connecting block 206. A first hollow groove 208 is formed in the inner cavity of the fixing block 202. A rack is rotatably connected to the inner cavity of the first hollow groove 208. The teeth of the gear 209 mesh with the teeth of the rack 207. The inner cavity of the second hollow groove 210 is rotatably connected to the rotating block 211. One side of the rotating block 211 is fixedly connected to one side of the gear 209. The surface of the rotating block 211 is fixedly connected to the ratchet 212. One side of the fixed block 202 is fixedly connected to the first fixed rod 213 and the second fixed rod 215. The surface of the first fixed rod 213 is rotatably connected to the pawl 214. The teeth of the pawl 214 mesh with the teeth of the ratchet 212. The surface of the pawl 214 is provided with an elastic piece 216. The top of the elastic piece 216 is fixedly connected to the bottom of the second fixed rod 215.

[0026] The rope 201 is connected to the handle of the power trowel 1. It can be connected to the first semi-ring block 203 via the fixing block 202. The second semi-ring block 204 is located on one side of the first semi-ring block 203 and can slide on that side. The first and second semi-ring blocks 203 overlap to form a circle, the interior of which can be used to place the worker's wrist. The interior of the T-slot 205 can be used to place the connecting block 206, allowing the connecting block 206 and the second semi-ring block 204 to slide on one side of the fixing block 202. The connecting block 206 can also be connected to the rack 207, which can also... The T-slot 205 allows for internal sliding, enabling the second semi-ring block 204 to move and drive the rack 207 to move together. The first hollow slot 208 can accommodate a gear 209, allowing it to mesh with the rack 207. This allows the rack 207 to rotate and drive the gear 209 to rotate. The second hollow slot 210 can accommodate a rotating block 211, which can connect to the gear 209. The rotating block 211 can also connect to a ratchet 212, allowing the gear 209 to drive the ratchet 212 to rotate together. The first fixed rod 213 supports the pawl 214, allowing the pawl 214 to engage with the ratchet 212. The ratchet 212 engages, and the pawl 214 also limits the ratchet 212, allowing it to rotate only in one direction. This allows the second half-ring block 204 to engage with the first half-ring block 203 to clamp around the worker's wrist after movement. Simultaneously, the unidirectional rotation of the ratchet 212 prevents the rack 207 and the second half-ring block 204 from falling downwards, thus ensuring a more stable grip on the wrist. Even when the worker's hand becomes sore or sweaty and detaches from the handle of the polishing machine 1, the first half-ring block 203 and the second half-ring block 204, along with the rope 201, can still effectively connect the polishing machine 1 to the wrist. The polishing machine 1 will not experience uncontrolled rotation. Due to the mobility of the second half-ring block 204, the first half-ring block 203 and the second half-ring block 204 can also be used by people with different wrist sizes, making it more widely applicable. When the first half-ring block 203 and the second half-ring block 204 need to be removed, simply use the other hand to rotate the pawl 214 to disengage it from the ratchet 212, allowing the ratchet 212 to rotate freely. The elastic plate 216 connected to the second fixing rod 215 can be used to reset the pawl 214, so that when the pawl 214 is lifted by the teeth of the ratchet 212, it can stably maintain engagement with the ratchet 212.

[0027] Reference Figure 4A support block 3 is fixedly connected to the inner cavity of the T-shaped groove 205. A spring 4 is fixedly connected to the bottom of the support block 3. The bottom of the spring 4 is fixedly connected to the top of the connecting block 206. The support block 3 can be used to connect the spring 4, so that the spring 4 can be connected to the connecting block 206 and compressed by the upward-moving connecting block 206. This allows the spring 4 to actively push the connecting block 206 and the second half-ring block 204 back when the pawl 214 disengages from the ratchet 212, thereby making it easier to remove the hand from the first half-ring block 203 and the second half-ring block 204.

[0028] Reference Figure 2 A fixing plate 5 is fixedly connected to the surface of the pawl 214. The fixing plate 5 is L-shaped and is connected to one side of the pawl 214. The L-shaped fixing plate 5 has a large area, which makes it easy to press with your fingers. This makes it more convenient for people to rotate the pawl 214.

[0029] Reference Figure 2 A limiting ring block 6 is provided on one side of the pawl 214. The inner cavity of the limiting ring block 6 is fixedly connected to the surface of the first fixing rod 213. The limiting ring block 6 can limit the pawl 214, so that when the pawl 214 rotates on the surface of the first fixing rod 213, it is not easy for it to detach from the first fixing rod 213.

[0030] Reference Figure 2 A pressure block 7 is fixedly connected to one side of the fixed block 202, and a push block 8 is fixedly connected to the bottom of the rack 207. The upper side of the pressure block 7 can be used to place people's index fingers, while the bottom of the push block 8 can be used to place people's thumbs. This makes it easier to move the second half ring block 204 by simply pinching the rack 207 upwards.

[0031] Reference Figure 3 A reinforcing block 9 is fixedly connected to the surface of the first semi-ring block 203. One side of the reinforcing block 9 is fixedly connected to one side of the fixing block 202. The reinforcing block 9 can strengthen the connection of the first semi-ring block 203, making the first semi-ring block 203 more secure on one side of the fixing block 202 and less prone to breakage or damage.

[0032] Reference Figure 2 The inner cavity of the first semi-ring block 203 is fixedly connected to the first sponge block 10, and the inner cavity of the second semi-ring block 204 is fixedly connected to the second sponge block 11. The first sponge block 10 and the second sponge block 11 can make the wrist more comfortable when the first semi-ring block 203 and the second semi-ring block 204 are put on people's wrists, and the wrists are less likely to feel uncomfortable due to the pressure of the first semi-ring block 203 and the second semi-ring block 204.

[0033] Working principle: When using this device, before using the power trowel 1, the operator can pass their hand through the first semi-ring block 203 and the second semi-ring block 204. Then, the operator moves the second semi-ring block 204 upwards. The second semi-ring block 204 will drive the rack 207 to move through the connecting block 206. The rack 207 will then drive the gear 209 to rotate. At this time, the gear 209 will drive the ratchet 212 to rotate through the rotating block 211. Then, the ratchet 212 will squeeze the pawl 214 to rotate. The 4th step will compress the elastic sheet 216, causing it to deform. The elastic sheet 216 will then spring the pawl 214 back to its original position, allowing the pawl 214 to remain engaged with the ratchet 212. The pawl 214 can also limit the gear 209 via the ratchet 212, ensuring that the gear 209 can only rotate in one direction. This prevents the rack 207 and the second semi-ring block 204 from moving back, thus allowing the first semi-ring block 203 and the second semi-ring block 204 to be stably clamped at the wrist. The operator can then grip the power polisher 1. When operating the polishing machine 1, even if the operator's hand becomes sore or sweaty and they detach from the handle, the first half-ring block 203 and the second half-ring block 204, along with the rope 201, can still effectively connect the polishing machine 1 to the wrist, preventing the polishing machine 1 from spinning uncontrollably. Furthermore, the mobility of the second half-ring block 204 allows both the first and second half-ring blocks 203 and 204 to be used by people with wrists of different sizes, thus broadening its applicability. After use, simply rotate the pawl 214 to disengage from the ratchet 212. At this time, the ratchet 212 and the gear 209 can rotate freely, allowing the rack 207 and the second half-ring block 204 to move back, thereby removing the first half-ring block 203 and the second half-ring block 204. This solves the problem of hand fatigue caused by prolonged gripping and exertion, and the issue that some people's palms are prone to sweating and becoming slippery, causing their hands to slip off the handle and the polishing machine 1 to rotate, which could easily injure people around them.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
